Almost a Quarter of all Lunar Ejecta Eventually Hits Earth

Take a look at the Moon through binoculars or a telescope and its clear that its been bombarded through history by space rocks. Some of the impacts are energetic enough that debris is ejected from the surface facer than the Moon’s escape velocity. Much of this rock finds its way to Earth and now, a team of researchers announce they have been simulating these events. They simulated asteroid impacts and tracked the debris that escaped the lunar surface and were surprised at just how much of the ejecta found its way to Earth.
