How does the Moon's curvature affect the apparent imposition of Tycho's rim for an observer standing on the crater floor?
Answer
The far edges of the rim sink beyond the local horizon, making it appear less imposing.
Because the Moon is substantially smaller in size compared to Earth, its curvature results in a much closer local horizon for any observer standing on its surface. When an observer is positioned on the floor of the Tycho crater, this geometric reality dictates that the far edges of the high crater rim will appear to sink down and disappear beyond that local horizon line. Consequently, the full vertical relief of the crater is not appreciated from the floor level; instead, the features are only fully observable and their height fully appreciated when viewed from an elevated position, such as from orbit or from Earth.
