Earth has one natural satellite and more than a thousand artificial satellites.
An artificial satellite is a man-made object injected into orbit around another object (The Space Station is an artificial satellite of the Earth). A natural satellite is a "natural" object that orbits around another object (The Moon is a natural satellite of the Earth).
In our Solar System, Planet Mercury and Planet Venus have no (0) satellites at all. No satellites orbit them. But if you are talking about planets with satellites and with the fewest moons, it is the Earth. Earth has only one natural satellite, THE MOON.
Yes, all planets in our solar system (except for Venus and Mercury) have at least one satellite - the gas planets are noted for often having more than 10. Earth is the only one to have artificial satelites remaining around it for great lengths of time, though.
A "natural satellite" is a body in space that revolves around (orbits) another body. Technically the planets are all satellites of the Sun, but the term is usually applied to the moons, moonlets, and other bodies circling a planet.The usage is required to differentiate moons, which were always satellites, from man-made or artificial satellites which were increasingly referenced as merely "satellites".Something not sent into space by humans, (eg not a sputnik, space station or rubbish). The moon, or even a captured asteroid, would be "natural"
So far, we know that Mercury and Venus do not have natural satellites, while the Earth, Mars, Jupiter, Saturn Uranus and Neptune do have natural moons. If we include artificial (man-made) satellites, then Venus has some as well. Of the extra-solar planets (planets that orbit other stars) we do not yet know of any moons. But it would be impossible for our current technology to detect the moons of planets so far away. Give us a few more years, and we may be able to answer those questions.
The only NATURAL satellite of the Earth is the Moon. There are more than a thousand artificial satellites of the Earth.
A great number of artificial satellites. At any given time, the Earth may have one or more small natural satellites (temporarily captured asteroids) as well.
It really depends on what you mean by a satellite. There are approximately 2465 artificial satellites orbitting earth. See: http://en.wikipedia.org/wiki/Satellite for more information.
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.
Yes. More specifically, it is sometimes called a "natural satellite", to distinguish it from the artificial (man-made) satellites that also orbit Earth.
There are 168 known natural satellites (moons) of the 8 major planets. There are also moons around 3 of the 5 dwarf planets (Pluto, Eris, and Haumea). There are more than 200 artificial satellites (or expired satellites) in Earth orbit or scattered throughout the solar system.
False. Only the so-called 'artificial' satellites are man-made. The 'natural' satellites didn't get that name because of the ingredients used to manufacture them. They are called 'natural' because they were created by Nature, not by man. Earth's Moon is an example of a natural satellite, not man-made. There are almost 100 more known examples elsewhere in the Solar System.
An artificial satellite is a man-made object injected into orbit around another object (The Space Station is an artificial satellite of the Earth). A natural satellite is a "natural" object that orbits around another object (The Moon is a natural satellite of the Earth).

They orbit the Earth because they experience a centripetal force due to the gravitational attraction between them and the Earth. Do you need more detail?
Most moons orbiting the various planets of our solar system are considered "satellites" - more specifically, "natural satellites". In addition, the more general use applies to the various space modules, etc., orbiting around the earth or around other planets of the solar system. As they are the result of human device, they are considered, "artificial Satellites". Sputnik 1, as the very first of these, acts as prime example.
The Moon is Earth's only significant natural satellite. There may be very small bodies orbiting Earth as well... by "very small" I mean "a few meters or less". These would be hard to detect. If you're talking about objects like Cruithne, it's not really a satellite of Earth.
