What is Satellite

A satellite is any object that moves in a curved path around a planet which has been intentionally placed into orbit. 

Sometimes a satellite orbit looks like an ellipse, a squashed circle that moves around two points known as foci.

The first artificial satellite, launched by Russia in late 1950 was about the size of a basketball. In this satellite, nothing but transmit a simple Morse code signal over and over.
