A satellite is a small object traveling around something bigger. The Moon is a natural satellite of Earth. A spacecraft launched into orbit around Earth is an artificial satellite. Since Sputnik-1, about 6,000 more satellites have been launched by 40 countries. Nearly 4,000 are still in orbit, and about 1,000 of them are still working.
