New study suggests that the asteroid was three times bigger than previously estimated and debris from the collision would have rained down on the Earth.
One of the Moon’s biggest craters was created by an asteroid more than 250km (150 miles) across about 3.8 billion years ago, forming Mare Imbrium known as the right eye of the “Man in the Moon”.
Some think the asteroid punched through the moon crust allowing the a lake of magma to pour out onto the surface changing the moon to a dead planet.
