Suppose you lived in the crater Copernicus on the side of the Moon facing Earth.

How often would the Sun rise?

How often would Earth set?

During what fraction of the time would you be able to see the stars?

Answer and Explanation:

In case, I lived in the Crater Copernicus on Moon's side facing the Earth then:

On moon, as it orbits the Earth, it takes 29 and a half days to complete one cycle of sunrise and sunset. So, the would rise once in 29 and a half day. The moon orbits the Earth in such a way that the its same side faces the Earth always which concludes that the Earth is overhead every time resulting in no Earth rise or Earth set on Moon. Due to the thin atmosphere, it can't impart any specific color to the sky on the moon as a result of which the moon's sky is always black and hence, stars can be seen every time.
