A satellite is an artificial object that is deliberately sent into orbit in space, usually in order to send, receive or bounce back information to different areas of Earth. Artificial satellites are man-made satellites, they differ to natural satellites such as the Moon which orbits Earth and Earth itself which orbits the Sun.
Satellites move in a path around the Earth called an orbit. Every satellite must have an orbital path (remember, satellites that travel into deep space to look at distant planets are not true satellites, they are in fact space probes), and the type of path it takes is determined by the physics involved. satellite's orbit works because of a balance between two forces. The orbit is a combination of the satellite's velocity-the speed it is travelling in a straight line-and the force of the Earth's gravitational pull on the satellite.
