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.
Bodies that orbit planets or moons are called satellites.
Satellite. Satellites can be natural, like the Moon, or artificial like GPS satellites.
There are two types of satellites, Genuine Satellites, which are any body that orbit a planet. For instance, our moon is a satellite of the earth, and there are artificial satellites which are man made objects that orbit a planet. These range from few tens of millions, to few hundred millions.
The different artificial satellites launched are Low Earth Orbiting Satellites for Remote sensing, Medium Earth Orbiting Satellites like GPS , Geo Stationary Orbiting Satellites for Communication and Molnia Satellites again for Communication. These are the different artificial Satellite orbiting the Planet Earth.
The orbit of each planet it the path it takes as it rotates round the Sun under the influence of the force of gravity. Every planet has a separate orbit and the orbits all follow Kepler's three laws of planetary motion.
These are called satellites. A lot of planets have natural satellites called moons, which are in orbit around the planet. An artificial satellite is one that is put there by man, it orbits the planet in a similar way.
They are launched by rockets.
First was sputnik, but anything from the Direct TV and XM radio satellites and telecommunication, GPS to the International Space Station are artificial satellites in Earth Orbit. There are artificial satellites currently in orbit around other planets as well.
Natural satellites are organic objects that orbit the earth such as the moon. Artificial satellites are objects humans propel through the earth's atmosphere in order to orbit the earth such as satellites for TV and radio signals.
