An orbit is a path. It's the way something goes around an object in space. The moon goes in orbit around Earth. You're in orbit right now! That's because Earth is following an orbit all the way around the sun. The International Space Station orbits Earth. An object in orbit is called a satellite. A satellite can be natural, like the moon. It can be human-made, like the space station. Earth is a natural satellite of the sun.

Planets, comets, asteroids and other objects orbit the sun. Many planets also have moons. These moons go in orbits around their planets.
