There are two kinds of satellites: the artificial and natural satellite.
One type of artificial satellite is called a navigation satellite. Two other kinds of artificial satellites are called weather satellites and communications satellites.
Well two of the four are ,the first is a Scientific satellites . The second is a Applications satellites.
geo stationary and polar orbiting
Artificial, Captured and Accreted
Man made,moon,sun
A natural body that rotates around a planet is a satellite, as in a moon. Man made satellites (artificial satellites) are made mostly of metal and rotate around earth looking at weather patterns or orbiting other planets for information. When they say Neptune has eleven satellites, they mean moons orbiting the planet, not man made ones. There doesn't have to be anyone there for there to be satellites of both kinds there.
There are many kinds of artificial satelliets orbit our earth they are used for many purposes for communication, GPS(global Positioning system). for television etc.
the plantetary satellites are made up of all kinds of electronic objects
The first artificial satellite that had a particular purpose (other than just for scientific research) was the Echo satellite; a large mylar balloon placed in orbit to reflect radio signals back to the Earth. Now, satellites are used for all kinds of communications; TV, cell phones, overseas phone calls, internet and such; weather satellites that help to predict the weather and track storms, and reconnaissance satellites that take photos of the Earth. Oh; GPS satellites.
No, because rings are not satellites, but the moons are satellites.
Mercury has no satellites.
It helpsus cure diseases, place satellites in orbit and send instantaneous electronic communications.
