one is that when a artificial satellite runs out of use it becomes space junk
Give two purposes of artificial satellites.
One type of artificial satellite is called a navigation satellite. Two other kinds of artificial satellites are called weather satellites and communications satellites.
There are two kinds of satellites: the artificial and natural satellite.
Venus has no natural satellites. It does have two artificial satellites (space probes). Venus is one of the two planets in our solar system (together with Mercury) that have no moon/natural satellite.
Two main types of satellites are: Communication(s) Remote Sensing

Currently there are only two planets with satellites orbiting them, Mars (a few of them) and Saturn (Cassini). All the planets excluding Uranus and Neptune have had satellites orbiting them at some point. We do also have two satellites orbiting minor objects and they are orbiting Comet 67-P (Rosetta) and the dwarf planet Ceres (Dawn).
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 USSR AKA Soviet Union AKA Russia were the first to succeed, followed by the USA.
Satellites cannot orbit one country. They may remain in geostationary orbit, but only at the equator. Therefore no satellite stays above only New Zealand.
Neither Mercury nor Venus have natural satellites. Earth has one natural satellite and several thousand artificial ones. All of the other planets have at least two (Mars) or more.
