Use Moon shadows to measure crater peaks

Practical astronomy projects for every level of expertise

The lunar surface is at its most striking when there are well-defined shadows. As well as being visually pleasing, the study of shadows cast by lunar mountains and craters can tell us a lot about these features. When we see a lunar crater from above it’s easy to think that the crater wall is uniform around the entire perimeter. However, if we look at the shape of the shadows cast by a crater wall, we can get
