> Throughout its history, the moon has endured countless asteroid impacts, leaving visible impact craters on its surface. These craters form when asteroids or meteorites collide with celestial bodies. Although most of the ejected lunar material falls back onto the moon, a fraction reaches Earth as meteorites. However, an even smaller fraction can escape both lunar and Earth’s gravitational pull, entering solar orbits akin to those of near-Earth asteroids.
So I interpret this to mean they think this came from an impact after the moon formed that broke a chunk off, not a fragment from the formation of the moon itself? If it was the latter I would think that it would be a great subject to study about the formation of the moon
- Terr_ 3y agoThat's my reading as well, that it's a knock-off rather than a sibling. If it was formed from the hypothesized Earth/Theia impact, would it have been (more) molten, and would that have affected its cooled shape?
