Asteroid 2024 YR4, which once appeared to be on a collision course with Earth, may hit the moon, which could create some problems for our planet.

The 55-feet-wide space rock is hurtling through space at a zippy 17,717 miles per hour, according to the space agency.

The space rock will make its closest approach—at a cosmically slight 183,000 miles from our planet—later today, according to the space agency.

Although it won’t hit Earth, an asteroid once labeled a “city killer” is now back in the spotlight — this time, because it might hit the moon.

Any uncertainty in the calculation of the object’s orbit causes variations in the predicted solution. Instead of one precise orbit, the calculation usually gives scientists a cloud of its possible ...

Asteroid 2024 YR4, which once appeared to be on a collision course with Earth, may hit the moon, which could create some problems for our planet.

Astronomers have been keeping a close watch on asteroid 2024 YR4 since its detection late last year. While initial observations sparked concern about a potential Earth impact, updated trajectory ...

The asteroid known as 2024 YR4 is out of sight yet still very much on scientists' minds. It now poses a threat to the moon, rather than Earth.

The latest observations of the asteroid in early June, before YR4 disappeared from view, have improved astronomers’ knowledge of where it will be in seven years by almost 20%, according to NASA. That ...

In the new study, researchers set out to calculate just how likely it is that an asteroid could hit Earth during the average ...
