The moon orbits Earth. When it orbits, it travels in a circle around Earth. There is a force between Earth and the moon called gravity. Because of gravity, larger objects pull smaller ones toward them. Earth is larger than the moon, so Earth pulls on the moon. At the same time, Earth is being pulled by the sun. The sun is larger than Earth. The balance between those two “pulls” is what keeps the moon in orbit around Earth. 
People say the moon shines. However, the moon does not actually have any light of its own. What we see as its light is really the sun’s light reflecting off of the moon. As the moon orbits Earth, Earth orbits the sun. We see different amount of light on the moon depending on its position. We call the changes in the moon’s appearance Lunar phases.
