Motion of the Moon

The Moon is one of the largest celestial objects in our sky. We are so accustomed to its motions that it may go unnoticed for long periods of time. Many people are unaware that the Moon is visible during the day at certain times, depending on its phase.

Yet the Moon has a daily influence on our lives. Even though it is small, it is close to us and it's gravity causes the ocean tides. We use its orbit to define a fundamental unit of time for us: the month.
