Orbits
An orbit is the path an object in space travels around another. Lots of objects in the Universe orbit others. The Moon orbits the Earth.
- Why do orbits happen?
Orbits happen because of gravity and something called momentum. The Moon's momentum wants to carry it off into space in a straight line. The Earth's gravity pulls the Moon back towards the Earth. The constant tug of war between these forces creates a curved path. The Moon orbits the Earth because the gravity and momentum balance out.
