The 10 biggest asteroids that pose a threat to Earth in 2020

<ul><li>Asteroid 2019 GT3 is going to fly past Earth on Friday at a speed of 49,000 kilometers. </li><li>The asteroid is about as big as a football stadium. </li><li>It's not on a collision course for Earth but is still one of the asteroids classified as 'potentially hazardous' by the National Aeronautics and Space Agency (NASA). </li></ul>The Earth is under <a href="https://www.businessinsider.in/what-is-asteroid-meteorite-and-meteor/articleshow/70654013.cms">constant threat</a> of asteroids but most fly past and don't actually hit the planet. Asteroid 2019 GT3 is one such asteroid that is 'potentially hazardous' but will be at least 7.5 million kilometers away from the Earth. Asteroid 2019 GT3 is a new addition to the NASA's <a href="https://cneos.jpl.nasa.gov/ca/">Asteroid Watch</a> only discovered earlier this year in April 2019. It's about as big as a stadium with a diameter between 170 meters and 380 meters. When it blasts past Earth on 6 September 2019, it will be flying at a speed of 49,000 kilometers per hour. "Potentially hazardous asteroids are currently defined based on parameters that measure the asteroid's potential to make threatening close approaches to the Earth," states the Center for Near Earth Object Studies "Specifically, all asteroids with a minimum orbit intersection distance of 0.5 [astronomical units] or less and an absolute magnitude of 22.0 or less are considered PHAs," it added. Asteroid's 'potential' for destruction There's no chance of Asteroid 2019 GT3 striking Earth. Even if it were to somehow be on a collision course for the planet, the asteroid wouldn't cause any kind of '<a href="https://www.businessinsider.in/neil-degrasse-tyson-and-other-scientists-believe-asteroids-will-eventually-hit-earth/articleshow/70644547.cms">mass extinction</a>' but it would definitely take out a small city. Scientists believe that an asteroid impact would result in a <a href="https://www.businessinsider.in/what-happens-when-an-asteroid-actually-hits-earth/articleshow/70732006.cms">'nuclear'-like winter</a> on the planet. It would only take an asteroid as big as a house travelling at 48,000 kilometers an hour to have an <a href="https://www.businessinsider.in/the-last-major-asteroid-to-hit-earth-destroyed-500-square-kilometers-and-it-could-have-been-much-worse/articleshow/70782507.cms">impact equivalent</a> to that of the Hiroshima bomb blast. By that comparison, Asteroid 2019 GT3 is bigger and faster. And, it's even more concerning in light of even more massive asteroids that are planned to come uncomfortably close to Earth in the near future. <a href="https://www.businessinsider.in/an-asteroid-nearly-half-the-size-of-mount-everest-might-be-on-a-collision-course-for-earth-in-less-than-a-year/articleshow/70698774.cms">1992 OR2</a>, for instance, is half the size of Everest and will only be 6.4 million kilometers from Earth as it flies by on 29 April 2020.

A 'potentially hazardous' asteroid will whiz past earth at 49,000 km/hr on Friday

Japan has landed two hopping robots onto asteroid Ryugu as part of the Hayabusa2 mission. It's Japan's second mission to an asteroid, where it plans to return some samples of Ryugu to Earth by the early 2020s. So that scientists can study the samples with more sophisticated instruments and hopefuly uncover some of the biggest scientific mysteries of all. Following is a transcript of the video.On September 21, Japan's space agency made history. It became the first country to land not one, but two rovers onto an asteroid. Already, the unmanned rovers have sent back the first images while on the surface. And no, so far it's looking like there are no alien cities on its surface. But this mission, called Hayabusa2, could ultimately help solve one of the grandest scientific mysteries of all: Where did life on Earth come from?Scientists have been studying asteroids for years. NASA, for example, landed its N.E.A.R Shoemaker spacecraft on asteroid Eros in 2001. But its Japan's space agency that is the first to deploy a pair of rovers to explore an asteroid's surface. Japan launched the Hayabusa2 mission in December, 2014. So, it has already been about 3.5 years in the making.The spacecraft rendezvoused with its target in June 2018. Snapping a series of pictures that revealed the asteroid's shape. The asteroid of choice was 162173 Ryugu, or Ryugu for short. In Japanese it refers to a magical, underwater Dragon Palace. Now, the asteroid flies through space, around the sun ever 16 months. Conveniently between the orbits of Earth and Mars.Making it an ideal target for the mission. Which, if all goes according to plan, will return a sample of the asteroid to Earth by the early 2020s. As the spacecraft flew closer to the asteroid's surface, it prepared to deploy its first two unmanned rovers. But these guys aren't your typical space rover. They're slightly bigger than the size of a large iPhone. Measuring just 7 by 18 centimeters. And they won't be driving around on the asteroid's surface. They'll be hopping.Yup, you heard that right. Hopping. Japan designed the rovers with a spinning cylinder inside that gives it the power to hop about a few meters at a time. This reduces the risk of getting stuck on the rocky, uneven surface. But it doesn't come without it's own risk. Asteroids are relatively small and therefore have a weak gravitational pull. And even by asteroid standards, Ryugu is tiny. It's less than a kilometer across, making it no larger than a few city blocks. So, if the rovers hop too high, they could potentially go flying off into space. But so far, the mission looks good.The rovers have already achieved their first hop. Now, this may be the first time Japan has landed on an asteroid but it won't be the last. These two rovers are just the first of four that Japan aims to land on Ryugu. The other two rovers are scheduled to land within the next year. In the process, Japan hopes to collect and return a sample of Ryugu to Earth. So that scientists can study it in more detail, looking for traces of water and organic material. If it turns out that asteroids like Ryugu contain similar material that we see on Earth it would be strong evidence for the idea that life on Earth first came from an asteroids billions of years ago. But this is a mystery that we can only answer if we study asteroids directly.

Why Japan is landing hopping robots on an asteroid

<ul class="summary-list"><li><a href="https://www.businessinsider.com/listen-bloop-of-meteor-falling-to-mars-nasa-insight-lander-2022-9">NASA</a> is about to slam a spacecraft into an <a href="https://www.businessinsider.com/dinosaur-fossil-from-day-extinction-asteroid-hit-earth-scientists-claim-2022-4">asteroid</a> to nudge it into a new orbit.</li><li>The <a href="https://www.businessinsider.com/nasa-launches-dart-probe-into-collision-course-with-asteroid-2021-11">Double Asteroid Redirection Test (DART)</a> is practice for deflecting an asteroid away from Earth.</li></ul>NASA is about to slam a spacecraft into an <a href="https://www.businessinsider.com/astronomer-discover-youngest-asteroid-pair-ever-in-our-solar-system-2022-2">asteroid</a>, obliterating the probe and nudging the space rock.The Double Asteroid Redirection Test (DART) is aiming for an asteroid called Dimorphos, which is orbiting a giant asteroid called Didymos. By crashing into it, NASA hopes to push the smaller space rock into a new orbit closer to its parent asteroid. The impact, scheduled for Monday, is practice for deflecting dangerous asteroids away from our planet.<div type="image" title="Infographic showing the effect of DART spacecraft impact on the orbit of asteroid Dimorphos" height="1520" width="2600" msid="94501281" hostid="261"></div>Dimorphos is 163 meters (535 feet) wide — big enough to obliterate a city like New York. That's no cause for concern, since it isn't on an Earth-bound trajectory, and DART won't change its path through the solar system. But that makes it perfect practice for one of the biggest threats in our cosmic neighborhood: city-killer asteroids, clocking in at 140 meters (460 feet) or larger.Having a tried-and-true deflection method won't help protect Earth from asteroids if nobody sees them coming, though. Experts previously told Insider that <a href="https://www.businessinsider.com/nasa-asteroid-simulation-reveals-need-years-of-warning-2021-5">NASA would need five to 10 years</a> to build and launch a customized mission to deflect an incoming asteroid. To date, scientists have only identified 40% of city-killer asteroids orbiting near Earth, NASA estimates. Nobody knows where the rest of them are, or where they're going.<div type="image" title="asteroid dimorphos edited next to rome Colosseum showing they are the same size" height="2418" width="2000" msid="94501283" hostid="261"></div>"Of course, you can't use any mitigation techniques unless you know where the asteroids are," Amy Mainzer, an astronomer at the University of Arizona, told Insider.In 2005, Congress mandated that NASA catalogue 90% of those 140-meter-plus asteroids. Mainzer has been working on a space telescope called Near-Earth Object (NEO) Surveyor, which is designed to fulfill that goal."This is one of the long list of risks that are out there to life on our planet," Mainzer said. "It's something we should just go cross off our list of worries. And the way we do that, is we go look for the asteroids, in my opinion."NEO Surveyor has made slow progress, though, and it just took another big hit.At the beginning of 2022, the mission got an infusion of $143.2 million to propel it toward launch. But NASA has since rescinded $33 million of that budget for this year, according to Mainzer, and slashed the project's budget by $100 million for <a href="https://www.nasa.gov/sites/default/files/atoms/files/fy23_nasa_budget_request_full_opt.pdf">2023</a>. NASA estimates that will delay the telescope at least two years, so it will launch in 2028 at the earliest."We are obviously disappointed about the budget cuts, because we know that it creates a less efficient project. It's going to make it cost more and take longer," Mainzer said.<h2>Smaller asteroids are already sneaking up on us</h2>Asteroids have already surprised humans a few times in recent years.<div type="image" title="asteroid russia Chelyabinsk" height="3744" width="5616" msid="94501284" hostid="261"></div>In 2013, a house-sized asteroid screamed into the skies above Chelyabinsk, Russia, and exploded. The blast sent out a shock wave that broke windows, damaged buildings, and injured more than 1,400 people. No one on Earth saw it coming. That same day, a <a href="https://www.npr.org/sections/thetwo-way/2013/02/15/172080937/no-link-between-meteor-that-hurt-hundreds-and-asteroid-about-to-fly-by">larger asteroid</a> came within 17,000 miles of the planet.Jim Bridenstine, who served as the Trump administration's NASA administrator, said in 2019 that the agency's <a href="https://www.businessinsider.com/nasa-threat-of-meteor-crashing-into-earth-is-bigger-than-you-think-2019-5">modeling</a> suggested an event like the Chelyabinsk meteor occurs about every 60 years.But the Chelyabinsk rock was small — about 50 feet wide. In 2019, a 427-foot, <a href="https://www.businessinsider.com/asteroid-flies-close-to-earth-surprising-scientists-2019-7">"city-killer" space rock</a> flew within 45,000 miles of Earth, and NASA had almost no warning about that either.<div type="image" title="people in winter coats gather around large dark rock wrapped in straps and rope" height="1665" width="2220" msid="94501285" hostid="261"></div>Then in 2020, an asteroid the size of a car passed closer to Earth than any known space rock had ever come without crashing. It missed our planet by about 1,830 miles. Astronomers didn't know the asteroid existed until about six hours after it whizzed by. Nobody saw it coming, because it was approaching from the direction of the sun.Telescopes on the ground can only observe the sky at night, which means they miss almost everything that flies at us from the sun. NEO Surveyor, from its perch in Earth's orbit, would be able to spot such space rocks. Since it would use infrared light, it could also spot asteroids that are too dark for Earth-based telescopes.<h2>The asteroid-spying telescope is suffering further delays</h2><div type="image" title="neocam asteroid hunter spacecraft discovery nasa jpl caltech" height="1476" width="1968" msid="94501286" hostid="261"></div>Mainzer first submitted the idea for an asteroid-hunting space telescope in 2006. NASA declined to take it on as a mission, funding other projects instead. She submitted proposals in 2010 and 2015 as well, but the agency kept passing.NEO Surveyor finally <a href="https://www.businessinsider.com/nasa-space-telescope-to-detect-deadly-asteroids-2019-9">became an official NASA mission</a> in 2019. Then the project languished in what NASA calls "Phase A" — a stage focusing on design and technology development. Last year, NEO Surveyor passed a key review and moved into Phase B, allowing Mainzer and her team to start building prototypes and developing hardware and software.Then Congress and President Joe Biden approved a budget of $143.2 million for the telescope in 2022 (later chopped to $110 million). That's a significant increase from the $28 million the mission received in 2021, and it allowed the team to make "significant" progress in all elements of the telescope's design, Mainzer said. But the agency's 2023 budget proposal allots just $40 million to the project. Once in orbit, NEO Surveyor is expected to spend 10 years boosting NASA's catalogue from 40% of city-killing asteroids up to 90%. After that, researchers can move on to smaller classes of asteroid, like the one that shocked Chelyabinsk."If you do a good thorough search, you might find that there are no potentially hazardous objects on the impact trajectory. And that would be great," Mainzer said. "It's reasonably straightforward to go find out the answer, so we should go do that."If the DART impact goes according to plan on Monday, NASA will be better equipped to divert any Earth-bound asteroid NEO Surveyor might discover.September 23, 2022: This story has been updated to reflect the budget cut for NASA's Near-Earth Object Surveyor project.
