66. When you're on the Moon, can you see Earth? (A K2S Question)

From The Space Library

There's about 41 percent of the near side of the Moon where the Earth is always in the sky. There's about 18 percent of the Moon around the edges where the Earth will occasionally dip below the horizon, due to a phenomenon called libration. About 41percent of the far side never sees the Earth. The Earth seen from the Moon will be a spectacular sight, being four times as large as the Moon we observe from Earth. It will appear as a very beautiful blue, white, green and brown sphere in a perfectly black sky.
