One obvious one...it's the moon! There are however, several other large objects orbiting the earth and a 6th apart from the moon and the other four has been recently discovered. Capture by gravity by the earth of a new satellite is almost impossible. There would have to be specific forces (usually friction from dust, or perhaps the moons gravitational pull) that would allow for a new object to begin orbiting the Earth.
New smaller objects may appear and disappear, but the Moon will be Earth's only long term companion for quite some time. Eventually, however, it too will be lost. Currently, Luna is moving away from the earth at a rate of about two inches per year.

The answer is so unpredictible, that you won't believe it! Right now there are 2,271 satellites in orbit around the Earth. Russia has the most satellites in orbit (1,324 satellites), followed by the U.S. with 658 satellites. Wouldn't there have been a collision by now? Weird, right. It's totally weird.
Nobody's really sure. There's a lot of junk in orbit. The National Space Science Data Center currently lists almost 7000 known spacecraft. Not all of those are still in orbit, of course, but a lot of other stuff is... booster stages, debris of former satellites, and so on.
Several thousand. Some of these are actual satellites that were intentionally launched into orbit; many more are fragments of the launch booster, or debris from the collisions of a couple of satellites. At least one was a toolbag dropped from an astronaut on a space walk from the ISS, although this may have deorbited already.
NASA is tracking about 19,000 separate objects each at least 1 inch in diameter, but a lot of that falls into the category of "space junk".
The Goddard Space Flight Center's lists 2,271 sate llites currently in orbit. Russia has the most satellites currently in orbit, with 1,324 satellites, followed by the U.S. with 658.
Around 26,000 space objects are orbiting Earth, only 560 are operational satellites.
The largest earth-orbiting man-made satellite is the International Space Station. Its orbit averages about 240 miles from the surface.
Earth has exactly one natural satellite. Its formal name
is "Luna", but most folks just call it "the moon".
The moon, at an average distance of 238,860 miles.
The moon is the nearest natural satellite, at an average distance of 384,400 km.
The moon. It is the earth's only natural satellite.The Earth's largest satellite is the moon, also known as luna.
A moon is a natural satellite, as opposed to an artificial satellite, which is a man-made object in orbit.
A Satellite (like our moon) Orbiting bodies are in fact orbiting each other, so that there are binary stars (two stars of about equal size) that are orbiting each other, or even binary planets.
This is a very vague question. First what planets are you referring to? Second, define "satellites" - Earth's moon is a satellite, but so is every single rock orbiting Saturn. We also send man-made satellites to orbit other planets. Restate your question. And lurn2google.
Satellite pictures are taken through the satellite and sent to Earth via satellite waves.

An "artificial satellite" Something orbiting something else is by definition a satellite. If the satellite is man-made, it thus gains the characteristic of being artificial.
Yes. The earth has many man-made satellites orbiting the earth, but there's also one natural satellite. This satellite is the moon, orbiting earth at about 2288 miles per hour (3683 kilometers per hour)
A moon is a natural satellite, as opposed to an artificial satellite, which is a man-made object in orbit.
Because all other satellites orbiting the earth are man-made.
The International Space Station (ISS).
There are several man made satellites that orbit the Earth. The moon is the only satellite that orbits the Earth in a counter-clockwise fashion, from west to east.
A satellite is one object orbiting another, so the moon is a satellite of Earth. A man made satellite is one we have launched in to orbit. The first being Sputnik, launched by the Russians, to thousands orbiting now providing communications for us in this modern era along with entertainment and GPS.
It showed that orbiting the Earth was feasible, a vital step towards escaping Earth's gravity. (I've assumed that you mean a man-made satellite, rather than our Moon, which is also a satellite of the Earth.)
The answer is obviously, "the moon". But if you're asking about the largest "Man Made" satellite, the answer would be the international space station.
A Satellite (like our moon) Orbiting bodies are in fact orbiting each other, so that there are binary stars (two stars of about equal size) that are orbiting each other, or even binary planets.
IN COMMUNICATIONS: Satellite uses satellite (orbiting) relay-stations in Space but Terrestrial uses cable or antenna-to-antenna signals based entirely on Earth to broadcast your television, radio or cell-phone :) ++++ IN ASTRONOMY: Terrestrial means Earth- (or planet-) bound; a Satellite is any natural or man-made object that orbits a planet. The Moon is a satellite of the Earth.
