During a session on April 30, scientists will discuss everything from how to observe the event to hypothetical missions we could send out to the asteroid. "In fact, as best as we can tell, no large object is likely to strike the Earth any time in the next several hundred years.". By 7 p.m. EDT, the asteroid will have crossed over the United States. Occasionally, asteroid and comets will come close enough to Earth for NASA's automated systems to track their orbits. © 1996-2015 National Geographic Society, © 2015- The Arecibo Observatory captured this radar image of the big asteroid 1998 OR2 on April 18, 2020. Although the threat of an asteroid collision is slim for now, NASA Administrator Jim Bridenstine warned there may be a deadly asteroid in the near future. The entire cast and crew... Hulu is gearing up for one of its most awaited horror web series which is Books Of Blood. Astrophysicist Gianluca Masi already managed to snap a picture of OR2.

On March 4, USA, the US Space Research Agency NASA NASA (National Aeronautics and Space Administration) officially announced that it would pass near Asteroid Asteroid Earth at 5.45 am local time on April 29. The target body’s composition, strength and structure, how much material is ejected by the impact, and the angle at which the spacecraft comes in are all important factors. "But a big rock will hit Earth eventually and we currently have no defence.”. Due to the sheer scale of this comment community, we are not able to give each post the same level of attention, but we have preserved this area in the interests of open debate. The blue dots are the many man-made satellites that orbit our planet, and the pink represents the International Space Station. Home of the Daily and Sunday Express. Some space rocks are big enough and bright enough to warrant observation from NASA. All rights reserved. You can also choose to be emailed when someone replies to your comment. If humans are still around when that day comes, it would be prudent to have a plan for protecting the planet. Current calculations show that Apophis still has a small chance of impacting Earth, less than 1 in 100,000 many decades from now, but future measurements of its position can be expected to rule out any possible impacts. Since my childhood, I developed an interest in music and composing songs which in return became my passion for writing content and stories. Although a “kinetic impactor” strategy is well understood, a number of variables control whether the impact would successfully deflect an asteroid, Syal says. Luckily, another team rediscovered the asteroid at the Siding Spring Survey in Australia later that year. But it won’t be a satellite or an airplane—it will be a 340-meter-wide near-Earth asteroid called 99942 Apophis that will cruise harmlessly by Earth, about 19,000 miles (31,000 km) above the surface. "Both are classified as 'potentially hazardous objects' because they pass periodically near Earth's orbit," said NASA in 1998. “We already know that the close encounter with Earth will change Apophis’ orbit, but our models also show the close approach could change the way this asteroid spins, and it is possible that there will be some surface changes, like small avalanches,” said Davide Farnocchia, an astronomer at JPL’s Center for Near Earth Objects Studies (CNEOS), who is co-chairing the April 30 session on Apophis with Brozović. The most insightful comments on all subjects will be published daily in dedicated articles. A 'close' passage astronomically can be very far away in human terms. It’s roughly the size of asteroids that can obliterate cities. The astronomers were only able to detect the asteroid for two days before technical and weather issues prevented further observations. On its next approach to our planet in 2078, it will be much closer, swinging within about a million miles of Earth. I am Piyush from the nation's capital, Delhi. NASA estimates the asteroid is racing around the Sun at speeds of about 8.7km per second or 19,461.3mph (31,320kmh). The bigger asteroids, including 1998 OR2 and 1990 MU, could devastate life across the planet if they hit.

Although scientists have spotted small asteroids, on the order of 5-10 meters, flying by Earth at a similar distance, asteroids the size of Apophis are far fewer in number and so do not pass this close to Earth as often. NASA has announced that on April 29th an asteroid the size of Everest will pass about 6 million kilometers from Earth: it will be visible to the naked eye from the balcony of the house. “If it wasn’t a binary, it would be basically impossible to measure with high precision,” says Megan Bruck Syal of Lawrence Livermore National Laboratory, who uses a mix of lab tests and supercomputers to model asteroid impacts.

Johnson says he expects the collision could decrease the moon’s 12-hour orbit by as much as seven minutes, although the team will consider the mission a success if that change is at least 70 seconds.
