Asteroid impacts shifted the Moon’s poles for billions of years

The moon’s poles shifted following asteroid impacts over billions of years, new research has found.

Astronomers have long used lunar craters to chart the history of moon and the whole solar system, because the pattern of destruction left behind by asteroid impacts paints a picture of the violent conditions found in the young solar system. The new research turns the tables on those studies by simulating the removal of thousands of craters and also accounting for the impacts of smaller craters, rewinding 4.25 billion years of lunar history.
