Old satellites orbiting near the Earth eventually fall back into the atmosphere and burn. Satellites orbiting farther away stay in orbit indefinitely.
Wheather satellites are used to take close pictures of the earth . Communication satellites are used for communication. Ex(in the old days if you sent a letter from Canada to Russia it would take 25 days. Now you write in MSN, it goes to the satellite and to the reciever.)
There are no known satellites of Mercury.
Triangulation of satellites requires three satellites that bank of one another simultaneously.
Yes but they are called natural satellites
CORRECT ANSWER:No.
If they are no longer used they will eventually fall from orbit and hopefully burn up in the atmosphere before hitting the earth.
Old satellites that are in orbit and still powered continue to perform their function. Old satellites that have no power and are still in orbit have no use. Those that fall from orbit have no use as the are destroyed on reentry. Old satellites that have never been launched could be used as museum exhibits.
The term "satellites" comes from the Latin satelles("attendants", members of a retinue), by way of the Old French for "hirelings". Natural satellites are followers, or "hangers-on" to a planet in its orbit.
Jupiter, Saturn and Uranus have MORE that 21 satellites.No planet has just 21 satellites - unless your are reading from a very old text book.

you can see a shadow on the planet and its so cool
No, because rings are not satellites, but the moons are satellites.
Mercury has no satellites.

Mercury has no satellites.
There are hundreds of thousands pieces of man-made material currently in orbit. A few thousand of them are actual useful satellites, things that we want to have up there; stuff like GPS satellites, communications satellites, weather observation stations, the International Space Station, and of course, DirecTV satellites. Most of them are "space junk"; satellites that have failed, or broken, or out of fuel. Old booster rocket engines. Collision debris, from when the Chinese shot down a satellite and smashed it into 100,000 pieces of litter in orbit, or when one of the Iridium satellites crashed into a Russian reconnaissance bird.
The old Soviet Union. first with satellites, then with manned spaceflight.
