YR4, which orbits the sun every four years and periodically crosses Earth's orbit. The nature of its orbit makes it a ...

If 2024 YR4 disappears from view before space agencies can rule out any chance of impact, the space rock will remain on the risk list until it is back in view in June 2028. Current estimates of the ...

Chances an asteroid may hit Earth in 2032 have again risen, though the risk remains tiny, astronomers say. Here's what to know about 2024 YR4.

YR4, which was discovered in December 2024, currently has a 2.3% chance of colliding with Earth in 2032, according to NASA. The percentage was initially calculated at just 1%, and scientists say that ...

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 ...

YR4 has a roughly 2 percent chance of hitting Earth in 2032, and “is large enough to cause localized damage,” NASA says.

Space agencies have systems in place to spot, track, and forecast the future orbits of potentially hazardous asteroids.

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

YR4: everything to know about the potential "city killer" space rock that has a 2.3% chance of striking Earth on Dec. 22, 2032.

The good news is that if Earth is incredibly unlucky and the asteroid does hit on Dec. 22, 2032, it will not destroy the world. However, if it impacts the Earth, the asteroid will ...

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 ...

YR4 became the highest-rated asteroid predicted to strike Earth, and although predictions for impact have lowered, not enough ...
