Most satelites, are barley out of the earths atmosphere, for example a GPS or weather satelite would go here, but some satelites are as far away as jupiter. They were shot off at top speed around 40 years ago and will continue to move farther into the universe.

YES
yes
u tell me
Satellites receive signals from Earth using antennas that are pointed towards the ground. The signals are sent from ground stations and relayed to the satellite. The satellite then processes the signal and can transmit it back to Earth or to another satellite.
A GPS uses satallites to identify location

"Distance" means how far two object are from one another. In this case, how far the Moon is from Earth, or how far the Sun is from Earth.
Both Mercury and Venus do not have Moons.

Far
