A shattered asteroid may have bombarded Earth 800 million years ago
A catastrophic asteroid breakup may have triggered a huge wave of impacts across the inner solar system about 800 million years ago. The debris was launched from near a gravitational gateway controlled by Jupiter, sending fragments toward Earth, the Moon, and Mars. The bombardment may explain ancient lunar craters and could have contributed to major climate and biological changes on Earth.
A study led by the Southwest Research Institute (SwRI) suggests that the fragmentation of an asteroid in the main belt may have triggered a bombardment of impacts on Earth and other planets in the inner solar system approximately 800 million years ago. The research relates the collision of a celestial body to the formation of lunar craters and to possible climatic and biological changes on Earth. Study links asteroid collision to impacts on Eart…
