Why does the Moon stay in orbit around Earth instead of flying off in a straight line into space?

The Moon has no motion of its own, so it simply hangs near Earth. Earth's gravity pulls on the Moon, continually changing its straight-line motion into a curved orbit. The Sun's gravity holds the Moon tightly against Earth's path. Earth's magnetic field traps the Moon in a circular path.

Correct Answer:

Earth's gravity pulls on the Moon, continually changing its straight-line motion into a curved orbit.
