Question

Quizplus · Accepted Answer

The Moon rotates on its axis once every 27.3 days, which means that there is about one lunar day and one lunar night each month. During a lunar day, the Sun would rise and set just like on Earth, but because the lunar day and night are each about two weeks long, there would be long periods of daylight and darkness. Therefore, as seen by a resident of Tranquility Base, the Sun would rise and set about once each month.
