Let’s learn about satellites



A satellite is an object that orbits a planet. The moon is a natural satellite. So are the 82 known moons of Saturn. But there are also artificial satellites. These objects do lots of different jobs for people on Earth. They beam television signals from one side of the country to the other. They’re what lets the global position system (GPS) help you navigate. They monitor our planet. And they look out into deep space.
