Scientists detected Asteroid 2024 YR4. It may hit the Moon. There is a 4% chance of impact. A collision could create a large crater. Lunar debris might trigger meteor showers on Earth. This poses a risk to thousands of satellites.

An asteroid having the size of a 15-story building might slam into the Moon in 2032. If it does, Earth could see a meteor shower.

The asteroid known as 2024 YR4 is out of sight yet still very much on scientists' minds as its revised trajectory is now drawing attention to another possible target: the moon.
