In order to understand how satellites stay in orbit, we need to first look at gravity. Everything that mass has a gravitational field. Right now, your computer's gravitational field is pulling on you, and your gravitational field is pulling on the computer.

Speed. Although all satellites (including the Moon) are constantly falling towards the Earth, they are moving across in a path that takes them beyond the Earth as they fall - so are literally falling all the time. However, because the Ear...

Evenutally satellites stop working for various reasons. Depending on the orbit of the satellite one of two things occur. Satellites in low earth orbit will eventually burn up in the Earth's atmosphere. Satellites in geostationary orbit are moved further out into a less desirable orbit.

A satellite is moving. Like anything, it's trying to move in a straight line. It should just head straight out of the solar system. Instead, something is keeping it from getting away. That sometime is gravity. The gravity is holding it just...

What actually happens is that the satellite is falling towards the Earth, but it is moving forwards fast enough so that the Earth stays at the same height. You can understand more of this by looking at the centripetal/fugal force (depending on which books you read), F=(mv^2)/r, ... MadSci Network: Astronomy...

When a satellite is held in orbit, what is it orbiting relative to? What's so special about the orbit of geosynchronous satellites? ... Geosynchronous satellites are man-made satellites that orbit the Earth. They always orbit the Earth at the same height above the Earth (35,785 kilometers). But there is something even...

How do satellites orbit the earth? Why don't they fall straight to the ground like everything else? ... On earth, it's not so easy because satellites have to get up above the atmosphere and into the vacuum of space to orbit for any length of time. 200 miles (320 km) up is about the minimum to avoid atmospheric interference.
