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 ...

While it’s likely that the asteroid will harmlessly whiz by Earth, as Apophis is expected to do in 2029 (when multiple spacecraft are expected to study it), it’s crucial for astronomers to ...

it initially carried a 2.7% chance of impacting Earth during its 2029 flyby – then a record. While YR4's impact odds have unseated Apophis, the larger asteroid still briefly hit a higher rating ...

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 ...

On the way to investigate the scene of a historic asteroid collision, a European spacecraft swung by Mars and captured rare ...

The asteroid also now rates as a 0 out of 10 on ... 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, astronomers ...

New observations have dramatically reduced the chances of asteroid 2024 YR4 hitting Earth in 2032, lowering the risk to ...

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 ...

That exceeds the threat once posed by Apophis, a much larger asteroid that was discovered in 2004. Astronomers initially calculated its chances of hitting Earth in 2029 at 2.7 percent. Further ...
