Satellite radio is like a special kind of radio that you can use to listen to more stations than regular radio. Instead of using radio waves like regular radio stations, satellite radio uses satellites in space. A satellite is like a big TV or phone tower in the sky that can broadcast radio signals all around the world. To get satellite radio, you have to buy a special radio or put a special device in your car that can pick up the radio signals from the satellite. Once you do that, you can listen to hundreds of stations that don't come through regular radio.
