The asteroid’s impact probability will continue to evolve—likely diminishing to zero—but 2024 YR4 will officially remain an object of concern so long as its estimated chance of striking Earth remains ...

In the case of Apophis, further observations eventually allowed astronomers in 2021 to rule out the possibility of an impact when the asteroid makes a close flyby to Earth in 2029 and again in 2036.

The asteroid also now rates as a 0 out of 10 ... a better look at Apophis before and during its close approach to Earth in 2029. Though both YR4 and Apophis are no longer a risk to Earth ...

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 ...

Here are today's general risks from asteroids or comets both tiny and very large. Importantly, even relatively small rocks can still be threatening, as the surprise 56-foot (17-meter) rock that ...
