Solar System Summary 2: The Moon ASTR 1101 The Moon The Moon has a diameter of 3476 km. This is equal to 0.27 Earth diameters; the Moon is a perfect sphere.

The surface of the moon is most likely the most interest part of it because it is a story in geological features. When looking at the moon you can almost imagine the scenario that caused the features, like the impact of asteroids causing the craters, and the moonquakes causing the sinuous riles.
