The Moon and the planets move through the sky by a path called ecliptic (the ecliptic serves as the center of a region called the zodiac). As all they move close to the same path, sometimes they appear in conjunction, that is one over the other. In the case of the Moon, it is always the planet that goes beneath because the Moon is always closer to Earth.

Here we see a conjunction between the Moon and Mars. It was recorded by José E. García Batarse from Mexico on 2003-07-17.
