An artificial satellite is a manufactured object that continuously orbits Earth or some other body in space. Most artificial satellites orbit Earth. People use them to study the universe, help forecast the weather, transfer telephone calls over the oceans, assist in the navigation of ships and aircraft, monitor crops and other resources, and support military activities.
Artificial satellites also have orbited the moon, the sun, asteroids, and the planets Venus, Mars, and Jupiter. Such satellites mainly gather information about the bodies they orbit.

Piloted spacecraft in orbit, such as space capsules, space shuttle orbiters, and space stations, are also considered artificial satellites. So, too, are orbiting pieces of "space junk," such as burned-out rocket boosters and empty fuel tanks that have not fallen to Earth. But this article does not deal with these kinds of artificial satellites.

Artificial satellites differ from natural satellites, natural objects that orbit a planet. Earth's moon is a natural satellite.

A natural satellite is an object that orbits a planet or other body larger than itself and which is not man-made. Such objects are often called moons. Technically, the term could also refer to a planet orbiting a star, or even to a star orbiting a galactic center, but these uses are rare. Instead, the term is normally used to identify non-artificial satellites of planets, dwarf planets, or minor planets.

There are 240 known moons within the Solar System, including 162 orbiting the planets,[1] 4 orbiting dwarf planets, and dozens more orbiting small solar system bodies. Other stars and their planets also have natural satellites.

The large gas giants have extensive systems of moons, including half a dozen comparable in size to Earth's moon. Of the inner planets, Mercury and Venus have no moons at all; Earth has one large moon (the Moon); and Mars has two tiny moons, Phobos and Deimos. Among the dwarf planets, Ceres has no moons (though many objects in the asteroid belt do), Eris has one, Dysnomia, and Pluto has three known satellites, Nix, Hydra, and a large companion called Charon. The Pluto-Charon system is unusual in that the center of mass lies in open space between the two, a characteristic of a double planet system.

Natural Satellites are natural and had been made natural like the planets. The natural satellite of earth is moon.

Artificial satellites are man made and are used for the purpose of communication, weather cast, spying, remote sensing etc

Natural contraception is a lot like abstinence. That is, it relies on people not having sex when they actually want to have sex. The success rates of "natural conception" and abstinence are both quite high because any failures are blamed on the people, not the method. To compare the success rates, it's best to look at the entire populations involved. Look at the group whose choice is abstinence, look at the group whose choice is natural contraception, look at the group whose choice is the pill, condoms, etc. Then determine which group has the best rates of prevention of unwanted pregnancy. Time and time again, it's been clearly shown that abstinence and the rhythm method both lead to many unwanted pregnancies.
