Numerical simulations already offer valuable insights. Apophis. Discovered in June 2004, the asteroid is approximately 350 meters in diameter and about 27 million tons. For a few weeks ...

Early last week, 2024 YR4 briefly broke a record once reached by the asteroid Apophis after it was first spotted in 2004. At its peak threat level, 2024 YR4 reached a 3 on the Torino Scale and had ...

A similar scenario unfolded in 2004 with Apophis, an asteroid initially projected to have a 2.7% chance of striking Earth in 2029. Further observations ruled out an impact. NASA did note ...

For an hour, HERA flew as close as 5,600 kilometers from the Martian surface, at a speed of 33,480 kilometers an hour. It ...

This is a contrast to a more chaotic time in 2004, when the larger asteroid Apophis was found to have a 2.7% chance of impact. “We’ve come a long way,” says Moissl. The risk that YR4 poses ...

Chances an asteroid may hit Earth in 2032 dropped to near zero, astronomers say. Here's what to know about 2024 YR4.

New observations have dramatically reduced the chances of asteroid 2024 YR4 hitting Earth in 2032, lowering the risk to minimal levels, but its extraordinarily close approach will offer astronomers th ...

The asteroid also now rates as a 0 out of 10 on ... NASA and the European Space Agency are also interested in getting a better look at Apophis before and during its close approach to Earth in ...

Agency looking at ways to use planet-threatening rocks’ tiny gravitational fields to slightly alter their trajectories ...

The last time was about 20 years ago, with the asteroid Apophis in 2004, which reached a couple of percent for a brief period in time before the uncertainty region could be constrained.

Hollywood films would have you believe that the best way to deal with an Earth-threatening asteroid is to blast it out of ...
