  • 5 Horrible Asteroids in Direction to Earth And Its Date Of Collision.

    10:00

    Asteroids, those dangerous objects capable of wiping out the entire civilizations, are found in millions in space.
    Most of them revolve around the solar system, mainly between the orbits of Mars and Jupiter.
    But the frightening thing is that according to different data collected by science, there are a number of asteroids that are approaching the earth and some of them even have a date for their collision with our planet.
    Get ready, because this time, we will review some asteroids that are in the direction of the earth and their possible date of collision.

    Before we start, we don't want to alarm you, as many asteroids have passed through the earth throughout history and have rarely posed a threat to the planet. Although some of the asteroids listed below have an impact date, this is not accurate, as many of them change their trajectory over the years.

    Knowing this, let's get started.

  • A Gigantic Asteroid Is Headed Our Way! Will It Hit Earth In 2021?

    3:48

    Apophis, the most infamous asteroid in history, is coming for a visit. There are millions of asteroids lurking in the solar system. About 66 million years ago, a 10-km wide asteroid struck the Earth and wiped out the dinosaurs. This caused the Cretaceous-Paleogene mass extinction. It was the fifth and the latest mass extinction event in the history of Earth. Since these rocky objects can cause disasters on our planet, tracking them is an important thing to do.

    Scientists have been tracking a 1000-feet wide asteroid called Apophis. Like all near-Earth asteroids, it has been rattling around the inner solar system for millennia. And now it is coming for a visit on March 5, 2021. The initial observations had indicated that Apophis would hit Earth or the Moon on April 13, 2029. According to calculations, the probability for such an impact to occur is 2.7%. Mathematics shows the highest probability of impact on April 12, 2068!

    Since its discovery, optical and radio telescopes have been tracking Apophis as it is orbiting the sun. In its 2029 flyby, the asteroid will come within 19,800 miles of the Earth. This is close enough to come between the Earth and moon, 240,000 miles apart. In 2021, Apophis will be more than 40 times as distant as the moon is from Earth. To capture the rock's sharpest echoes, scientists are relying on two of their best telescopes. The first is the Goldstone Deep Space Communications Complex in California. The second is the Green Bank Telescope in West Virginia.
    The data obtained will eventually set up the stage to deal with the 2029 flyby. So Apophis's March 2021 flyby is definitely something worth looking up to!

  • NASA’s Plan to Stop an Asteroid Headed for Earth

    8:02

    Like this video about how NASA is preparing to stop an asteroid headed for earth, and subscribe here:

    Watch the next video in our series on Guardians of the Apocalypse:

    Estimates say that a vehicle-sized asteroid explodes in our atmosphere about once per year, often too high to make a noticeable impact.

    But in 2013, a small meteor exploded just 20 miles above Chelyabinsk, Russia that sent over 1,200 people to the hospital.

    Today, a team of experts from NASA’s Planetary Defense Coordination Office works diligently to find asteroids that travel near Earth’s orbit.

    They’ve released a plan in order to prevent a large-scale asteroid impact, and part of this plan is the DART mission.

    DART aims to travel to the asteroid Didymos in 2021 to demonstrate the tech that could be used to redirect an asteroid headed for Earth.

    It's a collaboration with the European Space Agency (ESA), whose Hera spacecraft will follow up and observe the results of the impact on the asteroid and map Didymos's surface and interior structure.

  • What If The Largest Asteroid Hit Earth?

    10:47

    #eldddir #eldddir_space #eldddir_disaster #eldddir_earth

  • Will An Asteroid Hit The Earth Again?

    14:00

    From the implications of it all, to what it might take to get rid of one on its way, join us as we explore the question of whether an asteroid will hit Earth.
    7. Why Should We Fear An Impact With An Asteroid?
    Anyone who knows how the Earth works knows that there is an inherit safety measure that protects us from most violent things in space, it's called the atmosphere. You may not realize it, but only does the atmosphere allow us to breathe and stay warm via keeping the gasses and heat within reach of us, it also protects us from things like harmful radiation and falling rocks from space.
    This is why things like meteorites exist. They come from larger entities, and yet by the time they reach the atmosphere, the intense heat caused by the object falling through the invisible layer of our planet ends up making the object really, really small. One that can harm people and singular objects, but rarely do. And when they do, it's not on a planetary scale.
    So should we not fear things like an asteroid coming to our planet? Just the opposite. Because typically, asteroids are so large and so dense that the atmosphere alone can't stop it. Or in this case, shrink it down to non-planet ending levels. So should one come our way in the modern age that we live in, there's no doubt in anyone's mind that we would be in trouble. And if you don't believe that, you need only look at our history, and the history of our solar system, for proof of that.
    6. We've Been Hit By Asteroids Before
    Pop quiz, what killed the dinosaurs? If you said an asteroid, you'd be correct. There is loads of evidence that states that the event that ended the lives of pretty much every dinosaur on the planet was caused by the impact of an asteroid hitting our planet. This in turn created the ice age, which drastically affected our planet and helped shape what it is now.
    You wouldn't be ignorant for thinking that this was the only time that the Earth has been hit by a major asteroid, but you would still be wrong. Believe it or not, over the course of its life the Earth has been hit by MANY asteroids. The proof of which is in the ground of certain areas. For when an asteroid, meteor or meteorite hits the ground, they leave a crater. And across the world, there are impact sites that are both visible and not. Many have eroded over the years, while others have adapted to the areas they're in.
    If you were to look at places like the moon, Mercury, and even Mars, you would see plenty of craters on the surface of those entities. In fact, many meteorites that have fallen to Earth from Mars have been because of asteroids hitting the planet.

    5. The Size Issue
    The phrase, the bigger they are the harder they fall honestly does apply to asteroids, and the bigger they are when they enter the atmosphere, the more likely they are to cause a massive event. Now, on the good news side, many asteroids that are of truly destructive weight and mass don't hit the Earth too often. But they do hit. Ones that are above 60 feet in diameter tend to hit the Earth about twice every one hundred years.
    4. Near Misses
    What's scarier than having a dangerous event happen? How about having a MUCH more dangerous event nearly happen? That 2013 incident for example was bad, but a mere 16 hours AFTER that one occurred, another major asteroid came to Earth, but it missed it. What's more, that asteroid was about 100 feet wide, so it would've caused much more damage if it had come even somewhat close to the Earth's surface.
    3. What Can We Do About Asteroids?
    There's a lot of understandable fear in regards to asteroids, and since we now have much better technology, it goes to reason that there are people preparing to fight them off should one ever come our way. So, with that being said, can we stop a major asteroid before it hits the Earth and wipes us all out?
    Ironically enough, the answer is yes, no, and maybe. Teams at places like NASA are working hard to ensure that any and all comets, meteors, and asteroids within a certain range of Earth are known, identified, and then speculated about whether they'll hit Earth of not. This is a key part of the process because the last thing we need is to be caught surprise by one that is just miles away.
    2. What Would It Do?
    So if the worst should come to pass, what would it mean for the Earth as a whole? Well, as noted earlier, the location of where the asteroid would hit would be a big factor. If even a massive asteroid were to land in the middle of the Pacific Ocean, Atlantic Ocean, or somewhere near Antarctica, the effects would be felt on land, but maybe not as big as you might think.
    1. But How Likely Is It To Happen? ( asteroid 2019?)
    To end this, let's talk about the question of how likely it is that an extinction-level asteroid hits the Earth. In terms of round numbers, there are AT LEAST 14,000 asteroids in our area that have the potential to hit Earth..

    65 million years ago, a large asteroid collided with Earth near present-day Chicxulub, Mexico. The impact was a climactic event that likely contributed to dinosaur extinction. Today, Earth remains vulnerable to asteroid collisions. In recent history, space rocks have landed in The United States, Russia, and elsewhere. In the event of a potential asteroid collision, NASA has developed several options for dealing with the threat. Researchers at NASA’s Center for Near Earth Object Studies and Jet Propulsion Laboratory have proposed using blunt force, weaponized deflection or a theoretical tool called a gravity tractor to deflect impact. In addition to developing contingency plans, NASA scientists are also searching the sky for future asteroid threats.

  • NASA Plans to Slam a Spacecraft Into an Asteroid

    4:19

    What if a deadly asteroid was on a collision course to Earth? NASA and the ESA have come up with a solution.
    » Subscribe to Seeker!
    » Watch more Elements!

    Asteroids impacting Earth can be devastating—killing all the dinosaurs in existence level devastating. But even the asteroids that aren’t mass-extinction huge can be a serious threat.

    Every few thousand years Earth (a.k.a. you and I) get hit with a massive asteroid the size of the Great Pyramid of Giza, so what is the plan when we get hit with the next asteroid?

    We get hit with an asteroid about the size of the Great Pyramid of Giza every few thousand years, and when the next one hits it could cause massive damage to an entire region. So when we spot the next one coming, what’s the plan?

    Enter: NASA’s Planetary Defense Coordination office.

    The Planetary Defense Coordination office is tasked with coming up with ways to protect the planet from threats from outer space.

    And one of their great ideas is to smack a spacecraft head on with an oncoming asteroid to see if it can be slowed down and deflected. Members of NASA, the European Space Agency, and others are informally collaborating with a pair of missions that together are known as the Asteroid Impact and Deflection Assessment, or AIDA.

    NASA is up first with a mission called the Double Asteroid Redirection Test, or DART. The launch window opens on July 22, 2021, and the goal is to nail an asteroid by late September or early October the following year.

    Pretty cool, huh?

    The target DART is aiming at is one of a pair of binary asteroids called Didymos B. Didymos is Greek for twin, hence the Double part of DART.

    While the asteroid is not on a trajectory to hit Earth, it is an ideal candidate to see just how much of an impact will affect it because Didymos B is a moonlet 160 meters across that’s orbiting the much larger asteroid Didymos A, and as luck would have it, from our perspective it passes in front and behind the larger body, causing changes in the system’s brightness that we can measure.

    When DART hits Didymos B at 6.6 kilometers per second, the asteroid’s speed will change by a fraction of a percent, but that’s enough to change the time it takes to orbit Didymos A by several minutes. Enough to be detected by telescopes roughly 11 million kilometers away here on Earth.

    And not any old spacecraft will do when it comes to smashing into Didymos B.

    Find out more about the spacecraft that will be used on this asteroid deflection mission and more on this episode of Elements.

  • An Extinction Level Asteroid Impact With Neil deGrasse Tyson

    10:09

    An extinction level event from an asteroid impact is among the most common cause of extinction for many species in the history of life on Earth. Neil deGrasse Tyson explains in detail the possibility of an asteroid impact from the asteroid named Apophis after the ancient Egyptian deity who embodied chaos, its estimated diameter is between 1,115 and 1,214 feet. Additional observations cleared up the concern of a direct impact. Apophis is expected to pass close to Earth in 2029, 2036 and again in 2068.

    Neil deGrasse Tyson explains the details if Apophis were to hit near the coastline of North America.

    Asteroids are rocky fragments left over from the formation of the solar system about 4.6 billion years ago. Most of the asteroids orbit between Jupiter and Mars, where the Jupiter's gravity prevents them from ever combining into a larger body.

    There are, however, asteroids and comets that have been nudged by the gravitational attraction of nearby planets into orbits that allow them to enter the Earth's neighbourhood. These are called Near Earth objects or NEOs.

    NEOs are not yet well understood; they have only been tracked for a few years, and their orbits are usually very uncertain. It is difficult to predict how close an object will come to Earth, or where it will hit.

    An asteroid impact on Earth could have catastrophic consequences depending on the composition of the asteroid and the location of impact. An asteroid is likely to make a crater upon impact with Earth, causing massive destruction within a radius of hundreds of miles. This crater is likely to be hazardous for some time following the impact. Moreover, a major asteroid collision could cause general disruption to climate and weather systems on Earth.

    At the end of the Cretaceous Period, 65 million years ago, an asteroid hit Earth in the Yucatan Peninsula, Mexico, forming what is today called the Chicxulub impact crater. This impact caused a mass extinction in which 75% of plant and animal species on Earth became extinct, including all non-avian dinosaurs.

    According to Neal DeGrasse Tyson, If an asteroid is found to be on a collision course with Earth, instead of trying to blow it up, the main goal would be to nudge it out of its path, avoiding an unpleasant end to civilization.

  • What if Apophis Asteroid could hit the Earth in 2068

    3:28

    #ExploringSpaceS1E4
    A large asteroid will impact our planet in 2068, according to research conducted at the State University of St. Petersburg, Russia. It is a rocky body of 370 meters in diameter, discovered more than a decade ago and baptized Apophis 99942.
    NASA came to calm the waters, minimizing the power of Apophis. According to the US agency, there are only 1 in 250 thousand possibilities for the collision to occur in 2068. It should be noted that for this chaotic situation to occur, Apophis asteroid should move to a specific altitude through a narrow region in space, where the gravity of a planet (in this case the Earth) alters its orbit.
    “We can rule out a collision on the next approach to Earth, but then the orbit will change in a way that is not completely predictable at this time. That’s why we cannot predict behavior on a longer time scale, “said Alberto Cellino, of the Turin Astrophysics Observatory in Italy.

    It must be remembered that when Apophis asteroid was discovered in 2004, the scientific community pointed out a possibility of impact with the Earth by 2029 of 2.7%, a prognosis that was later discarded.

  • Will A Huge Asteroid Hit Earth in 2022? | NASA

    Nasa is tracking a devastating 230-kilotonne asteroid that could hit Earth in May 2022.

    Each day Earth is hit by 100 tons of sand-sized particles from space. every year a car size asteroid hits Earth's atmosphere and burns up before reaching the surface.

    Asteroid strikes are actually more common than most people think. In fact, there are many instances where potentially destructive asteroids came too close to Earth.

    However, dangerous asteroids the size of football fields are said to hit Earth about every 2,000 years, and asteroids large enough to destroy civilizations come once every few million years.

    One such asteroid is 2001 JF1, it could come very close to Earth in May of 2022. It was first discovered in 2009. Scientists estimate this massive asteroid to be around a whopping 420 feet across, or around 130 meters in diameter. For comparison this asteroid is about the size of the Great Pyramid of Egypt.

    Despite the one in 3,800 odds of the asteroid smashing into the Earth, the worst-case scenario will surely be a scene from an apocalypse movie.

    If this city-killer asteroid hits Earth, the impact would be equivalent to 230 kilotons of TNT. That is 15 times stronger than the atomic bomb that hit Hiroshima in 1945, which destroyed the whole city with 15 kilotons of force.

    Comet, meteor or Asteroid?
    Intro
    There is a vast amount of rocks and debris floating around in space. Around 100 tons of it falls to
    earth every day. You might have been lucky enough to have seen a shooting star, but do you know
    whether it is a comet, meteorite or an asteroid?
    what is the difference between these 3 objects? Why are we landing satellites on asteroids and
    could life have been brought to earth on one of these rocks?

    Main
    Comet
    A comet (also called a dirty snowball) is essentially ball of ice, rock and dust that orbits the sun,
    ranging in size from around 1km to 20km.
    Astronomers believe they are leftovers from the early formation of the solar system that reside in
    one of two places on the very outskirts of the solar system; The Kuiper belt and the Oort Cloud.
    These two areas are made up of small icy bodies (and Pluto) of frozen gases such as methane,
    ammonia, nitrogen and water mixed with rock and dust. Occasionally a comets orbit will be altered
    by a gravitational tug of another large object or through a collision with another body that might
    send it into the inner solar system or sometimes even straight towards the sun.
    As a comet starts to move closer the sun, it heats up and ice starts to evaporate and form a cloud
    around the nucleus. Solar winds from the sun push the cloud to make a tail on the comet, also called
    a coma. The coma creates a spectacular light show for us on earth and these tails can reach up to
    150km in length.

    Asteroid
    Nearly all Asteroids are odd shaped chunks of rock that orbit the sun in the asteroid belt between
    mars and Jupiter. Some though are thought to be made of metals like nickel and Iron.
    The asteroid belt is thought to be either leftover mass from a failed planet forming due to the close
    gravity pull of Jupiter or the leftovers from a planet that broke up due to a collision.
    They come in sizes from a few meters to just under a 1000kilometers wide. Ceres is the largest we
    have ever found and is 960km wide which is about as wide as Texas and big enough to be classed as
    a dwarf planet. Some asteroids also have their own moons!
    Also if you condensed all of the asteroids in the belt together they would still be smaller than our
    moon.

    Meteoroid
    Space debris smaller than asteroids are called meteoroids. These can be as big as a few meters and
    as small as a grain of sand. They are usually bits of asteroids that have collided or leftover debris
    from a comet.
    When a small meteoroid gets close enough to enter in the Earth’s atmosphere it starts to burn up
    completely and creates a dazzling trail of light due to the air resistance it encounters. This is called a
    meteor, or as we sometimes call them, shooting stars.
    Every year around mid July the Earth’s orbit takes us through the dust and debris left behind by a
    comet. This is called the Perseid meteor shower and creates an incredible display of shooting stars
    with around 80 shooting stars an hour. You can find out more about this and how to view the
    spectacle in the link at the end of the video or in the description below.
    90-95% are vaporized n their approach to earth but when a rock survives this and hits the earth’s
    surface, it is called a meteorite. They are usually about the size of a pebble but we have found a
    3-metre-wide 66 ton tablet shaped meteorite in Namibia that fell about 80,000 years ago.

    When the dinosaur-killing asteroid struck Earth, most of the impact energy was directed outwards and upwards into space. Only 1% of the force traveled down into the ground, but it was enough to ring the planet like a bell and wipeout species around the globe. Only those creatures able to seek shelter from the intense heat on the surface survived.

  • How do we know an asteroid hit Earth 66 million years ago?

    One theory for why the dinosaurs went extinct is that an asteroid hit Earth at the end of the Cretaceous period. But since no one was alive to see it, how can we know that it really happened? Astrophysicist Jackie Faherty reveals how clues found in sedimentary rock and on the ocean floor have helped scientists piece together this millennia-old mystery.

  • Will a Giant Meteorite Hit the Earth? April 2020

    1:19

    #Meteorit, #Asteroid, #29April2020, Will an Asteroid Hit Earth in April 2020?
    #EvdeKal, #StayHome, #WithMe,
    Clickbait headlines continue to stoke fears about doomsday asteroids.

    NASA warned that Asteroid 52768 (1998 OR2) could hit Earth in April 2020 and cause catastrophic danger.

    On April 29, 2020, a large asteroid is expected to fly by earth at a distance of approximately 4 million miles. That may be of interest to stargazers, but the previous sentence isn’t very alarming or attention-grabbing. Yet many media outlets wrote headlines about this incoming asteroid as if it posed an immediate and catastrophic threat to the planet.

    An article in the Daily Express, for instance, was headlined: “Asteroid warning: NASA tracks a 4KM asteroid approach – Could end civilisation if it hits.” The site used a similar message when promoting this article on Twitter:

    While these headlines may bring clicks, they also may lead readers to falsely believe that this asteroid poses an immediate threat to life on Earth. That isn’t the case.

    While Asteroid 52768 (1998 OR2) will approach Earth in April 2020, the asteroid is not expected to come within 3.9 million miles of the planet.

    NASA is constantly monitoring the skies for asteroids and meteors that pose a potential threat to Earth. When these near-Earth objects (NEOs) are discovered, NASA monitors them to find out when they will approach Earth, how fast they will be traveling, how large they are, and how close they will get. All of this data is publicly available on the Center for Near Earth Object Studies (CNEOS) website.

    Asteroid 52768 (1998 OR2) was first discovered (as its name implies) in 1998, so this asteroid isn’t making a sudden and scary appearance above Earth. NASA has been monitoring it for more than two decades and has learned quite a bit. For instance, the asteroid is relatively large with a diameter between 1.1 and 2.5 miles, and it will be traveling at just under 20,000 mph when it makes its closest approach to Earth.

    While an asteroid of this size would cause catastrophic damage if it hit Earth, there’s practically no chance that will happen in April 2020. According to NASA, this asteroid won’t come within 3.9 million miles of Earth. In other words, it will approach no closer than about 16 times the distance between us and the moon.

    Asteroid Watch, the official Twitter account of the CNEOS, attempted to quell fears about this asteroid, writing that it will “safely pass” Earth and that NASA did not issue a “warning” about a possible catastrophic collision.

    Asteroid 52768 (1998 OR2) is not currently listed on NASA’s list of potential future Earth impact events.

    On a daily basis, about one hundred tons of interplanetary material drifts down to the Earth’s surface. Most of the smallest interplanetary particles that reach the Earth’s surface are the tiny dust particles that are released by comets as their ices vaporize in the solar neighborhood. The vast majority of the larger interplanetary material that reaches the Earth’s surface originates as the collision fragments of asteroids that have run into one another some eons ago.

    With an average interval of about 10,000 years, rocky or iron asteroids larger than about 100 meters would be expected to reach the Earth’s surface and cause local disasters or produce the tidal waves that can inundate low lying coastal areas. On an average of every several hundred thousand years or so, asteroids larger than a kilometer could cause global disasters. In this case, the impact debris would spread throughout the Earth’s atmosphere so that plant life would suffer from acid rain, partial blocking of sunlight, and from the firestorms resulting from heated impact debris raining back down upon the Earth’s surface. Since their orbital paths often cross that of the Earth, collisions with

    No one should be overly concerned about an Earth impact of an asteroid or comet. The threat to any one person from auto accidents, disease, other natural disasters and a variety of other problems is much higher than the threat from NEOs. Over long periods of time, however, the chances of the Earth being impacted are not negligible so that some form of NEO insurance is

    NASA is currently tracking about 20,000 NEOs. While these objects routinely pass by Earth without incident, every now and again a media outlet will write an outlandish story about how one of these objects is posed to wipe out life on earth. While we’ve seen several of these fear-mongering rumors over the years,

  • Apophis and the asteroid threat

    3:58

  • Earth’s Scientists Can’t Stop NASA’s Killer Asteroid

    6:42

    WASHINGTON — NASA created a fictional asteroid and set it on course to hit Earth six months after being discovered by humanity’s early warning systems. Earth’s scientists worked together to stop the doomsday rock from hitting Earth, and this is what happened:

    NASA reports that it recently hosted a test to see if Earth’s best scientists could stop an asteroid from hitting the planet.

    In the scenario, a fictitious asteroid was detected six months before it would hit Earth. The participants in the simulation considered various missions in which spacecraft could try to destroy the asteroid or deflect it off its path.

    Most options to deflect an asteroid — such as deflection via a high-energy impact, or a “gravity tractor” or an “ion beam shepherd” — work by only slightly nudging the targeted space rock.

    If performed far enough in advance, that small nudge builds up to become a large shift in position by the time the asteroid gets near Earth.

    But participants concluded that such missions wouldn’t be able to get off the ground in the short amount of time before impact.

    However, they found that using a rocket to deliver a nuclear explosion on or next to the asteroid, could save the Earth.

    Unfortunately, a nuclear bomb would only be able to make a difference if the asteroid was relatively small, compared to the giants that had hit Earth in the past.

    Currently, Earth’s early warning system does inspire confidence. Comet Neowise, a 4.8 kilometer-wide chunk of space ice, passed within 64 million kilometers of Earth in July.

    Nobody knew this comet existed until a NASA space telescope discovered it approaching only four months earlier.

    In 2013, a meteor about 20 meters in diameter entered Earth’s atmosphere without warning.

    It exploded over Chelyabinsk, Russia, creating a shock wave that broke windows and damaged buildings across the region. More than 1,400 people were injured.

  • It Became Known When a Huge Asteroid Will Hit the Earth / Apophis

    The poster child for hazardous asteroids—named after an ancient Egyptian god of chaos—has no chance of striking the Earth over the next 100 years at the very least, according to a new NASA analysis. Prior to the latest analysis, a small chance remained that the space rock, known as 99942 Apophis, could collide with our planet in the year 2068. While calculations showed that this chance was tiny—one of the latest estimates suggested a probability of around one in 380,000—the new analysis has now definitively ruled out this possibility, with astronomers gaining a better understanding of the asteroid's orbit around the sun. The space rock, which is estimated to measure around 1,100 feet across, was discovered in 2004 and quickly gained notoriety after astronomers initially predicted that it had around a 2.7 percent chance of colliding with the Earth during a close approach in 2029. This is a relatively high probability and briefly caused concern in the astronomical community, given that an impact involving an object of this size would cause widespread devastation on our planet. But subsequent research ruled out a collision with our planet during the close approach in 2029, and indeed the asteroid's next close approach in 2036. This left only the tiny potential for an impact during the close approach in 2068. A 2068 impact is not in the realm of possibility anymore, and our calculations don't show any impact risk for at least the next 100 years, Davide Farnocchia from NASA's Center for Near-Earth Object Studies said in a statement. When I started working with asteroids after college, Apophis was the poster child for hazardous asteroids, Farnocchia said. There's a certain sense of satisfaction to see it removed from the risk list, and we're looking forward to the science we might uncover during its close approach in 2029. The list Farnocchia referred to is the Sentry Impact Risk Table maintained by CNEOS, which includes the handful of known asteroids with orbits that will take the objects so close to Earth that an impact cannot be ruled out. Astronomers were able to confidently rule out a collision in 2068 after analyzing observations of the space rock conducted during a recent, distant flyby when Apophis passed the Earth at a distance of more than 10 million miles. Although Apophis made a recent close approach with Earth, it was still nearly 10.6 million miles away. Even so, we were able to acquire incredibly precise information about its distance to an accuracy of about 150 meters, Marina Brozovic from NASA's Jet Propulsion Laboratory, said in a statement. This campaign not only helped us rule out any impact risk, it set us up for a wonderful science opportunity.

  • What If An Asteroid Strikes The Earth in 2020?

    7:41

    Why do asteroids strike Earth? Space is really empty and big, but there is also a lot of stuff out there, and Earth is a big target with big gravity, so things run into Earth or Earth runs into them.

    Should I be worried about asteroids striking the Earth? No, and yes. You shouldn’t lose sleep over it because damaging asteroids do not hit very often. But you should care about it: they have hit and dangerous asteroids will hit again, unless we prevent that from happening.
