The earth is a planet. An earth satellite is an artificial satellite that orbits the earth A geostationary satellite is an earth satellite that orbits at a height (approximately 22,000 miles) precisely determined to ensure that the satellite remains over the same spot on the earth's surface at all times, thus appearing from the earth to be stationary in the sky.

It depends on which orbit the satellite is in: * Low orbits are around 300 - 500 miles high * Geosynchronous orbits are around 23,000 miles up * Elliptical orbits vary * I think there are other orbits as well, but I am not sure
First.200 miles (320 km) up is about the minimum to avoid atmospheric interference.
The distance depends on the orbits of Earth and Saturn; the closest they'll be is about 1.2 billion km, and the farthest they'll be is about 1.67 km.

Yes; it is fairly far away, so it can cover almost half the Earth's surface - but not quite.
Geostationary satellites are in an orbit that's 22,282 mi (35,786 km) above the surface of the Earth. For more on Geostationary satellite orbits, visit http://www.idirect.net/Company/Satellite-Basics/How-Satellite-Works.aspx

The Vanishing point, i think. Vanishing point is where everything points to and fades out of view. It might be the background.
