Asteroid debris from Jupiter may have pummelled Earth for 150 million years

A large asteroid broke apart about 800 million years ago. This event sent many rocky pieces towards Earth, the Moon, and Mars. Scientists from the Southwest Research Institute studied this issue.

The asteroid collision likely happened in the main asteroid belt. This area is between Mars and Jupiter. It contains millions of asteroids that travel around the Sun. The fragments from the breakup may have caused many impacts on these planets over millions of years.

The researchers think this event can explain the large craters on the Moon. These craters date back to around 800 million years ago. The impacts may have also influenced Earth’s climate and the development of life.

The Moon shows many craters because it does not change much over time. Unlike Earth, it has no plate tectonics or weather to erase its surface. Scientists find it hard to study older impacts on Earth because its surface keeps changing.

The study mentions that the Eulalia asteroid family likely caused the breakup. The pieces from this incident spread out, increasing the chance of impacts on different planets, including Earth and Mars.
