The force of meteoroid strikes on the lunar exosphere

The lunar exosphere – the thin layer of gas surrounding the moon that’s one 25-trillionth the density of Earth’s atmosphere – is impacted by many things. Physical processes such as meteoroid stream impacts, the bombardment of helium and hydrogen particles from the sun, thermal absorption, and space weathering constantly modify the moon’s surface as they […]
