It has to travel at 17, miles per hour to stay in orbit. You may also know that the asteroid belt also moves around the Sun. But did you know our entire solar system is also in orbit? Our solar system is constantly orbiting the black hole at the center of the Milky Way Galaxy.

Now space also contains artificial satellites. These are objects made by humans. They are put into orbit by people.
