Hi, folks. Here's an old but favourite animation I did in 2013 depicting the Earth-Moon system in infancy. This is shortly after a Mars-sized body ('Theia') hit the proto-Earth. The Earth reformed, and the Moon coalesced out of the rest of the debris.

Animation showing the Earth and moon 4.5 billion years ago. Both bodies have very recent impact scars with partially melted surfaces. A ring of debris surrounds the larger body (Earth) and a smaller body (Moon) is embedded in this ring.
