The asteroid 2024 YR4 was, for a brief time, thought to be on a potential collision course with Earth. The 2024 YR4 collision scenario Though there’s only a small—though non-negligible—chance the asteroid 2024 YR4 will hit the moon, scientists are assessing how they could make the most of such a scenario. A massive molten rock pool In the potential collision scenario, 2024 YR4 would create a crater roughly 1 km wide and up to 260m deep. Using existing seismometers on the moon, scientists could shed new light on the moon’s interior and better understand its composition. For now, the chances of 2024 YR4 colliding with the moon are small.
