Do all satellites travel?
Yes, all satellites have to travel to get into space! But whenthey get there, they orbit around Earth differently depending on their purpose. For example, the International Space Station and the Hubble Space Telescope are in Low Earth Orbit. Satellites in Low Earth Orbit go around Earth less than 2000 km (1243 miles) high. There are also satellites that orbit at the same speed as Earth, such as weather satellites. These satellites have a geosynchronous orbit and move with the Earth to study the same spot at all times.
