Answer 1

Briefly, artificial satellites are some kinds of electric device that people send into space. These devices are programed to move around the earth in a certain orbit (just like the moon can move around the Earth ,you know. And it's called a natural satellite of the Earth.)  

Artificial satellites can be used for different purposes.

Answer 2

Artificial satellites are the satellites we launch into orbit (earth has thousands of these).  

A natural satellite is any "moon,"  (earth only has one of those.)

Benefits of artificial satellites:

*Better understanding of orbital physics

*A (slightly) larger area to triangulate star distances (look up: parallax and Hipparcos)

*Cell Phones

*Wireless Internet

*Google Earth

*Satellite Television (yes, those  satellite dishes are pointed up there for a reason)

*Satellite Radio (which I've always found somewhat peculiar terminology)

*Communication (pretty much all non-radio signal and non land-line communications are bounced off of satellites these days).

*Intelligence for the various millitaries...

*Any study that can be done from photographs/thermal images of the earth from satellites in orbit (global warming, vegitation, large storm activities, long-term atmospheric phenomenon, long-term cloud patterns, can all be studied from satellite photography... not everyone comes to the same conclusions all the time, but the information is provided).
