There are many satellites orbiting earth. There are the artificial satellites put in space by different countries. There is also the space junk like wrenches and parts of space exploration. There are even parts of asteroids.
Bottom line, a satellite is any object that orbits a planet or moon; or a celestial body orbiting another of larger size.

I am an Asronomer and I have no idea where you got your information, but, is more than 800 books covering the field of Astronomy I have NEVER read that a "moon" is considered of ever called a "planet". They are called "satelites" because they ORBIT "planets"...just as man-made satelites "orbit" the planets like Earth and Mars and Jupiter. By "definition", a "satelite" is an object or mass that "orbits" another body in the Solar System which are called "planets". There is NO moon or satelite within our Solar System that is called a planet. Beyond our Solar System, NO OTHER BODIES have ever been seen nor discovered that can be called a "planet" because even our most powerful telescopes don't have the power or means to "see" such great distances of celestrial bodies that don't emit their own "light" as the stars. That is why NO OTHER PLANETARY SYSTEM has NEVER been discovered...and NEVER WILL BE.
You should pick up the three-volume set of "Burnhams Celestrial Handbook"...you would learn invaluable information about these very subjects...and NO SERIOUS ASTRONOMER can be serious about the hobby or study of Astronomy without Burnhams Volumes, along with "Nortons' Star Atlas" of the heavens. I wish you luck in your studies as you learn about our Galaxy and the Universe in which we live. Apparently you need these valuable books for a better understanding ot the heavens.

Moons and satellites are essentailly the same thing: they both orbit around a planet. We normally think of satellites as being man-made objects orbiting Earth, but this is just a more modern usage of the word. Similarly we think of moons as being natural bodies that orbit a planet. These words can be used interchangably to describe natural bodies like our Moon (which is always capitalized to differentiate it from the others), but it would seem foolish to call a man-made object a moon even though there is nothing technically wrong with it.
However, a moon should never be considered a planet because they are two different things. A planet orbits a star, and a moon orbits a planet.

A satelite is a body in orbit around another body. For instance our moon is a satelite of earth. The earth is a satelite of our sun and so on. By definition a planet is a body in orbit around a star and a moon is a body in orbit around a planet. There are some moons that have atmosphere and molten cores with volcanoes and geysers. Some of the moons are mistakenly called "planet like" to refer to the conditions that are similar to conditions here on earth. Just keep the order in mind. Planets orbit stars...moons orbit planets.

on earth or on any other planet where its moon reflects the sun's light on it.
A natural satellite is a non-man-made object that orbits a planet or other body larger than itself. It is commonly referred to as a moon (not capitalized). The term natural satellite may also refer to a planet orbiting a star, as is the case with the eight or nine planets orbiting the Sun. There are 240 known moons within the Solar system, including 80 orbiting minor planets (not the bodies in the asteroid belt) and over 150 orbiting the planets. 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. Mercury and Venus have no moons at all; Earth has one large moon ("the Moon" or "Luna"); Mars has two tiny moons; and Pluto has at least three satellites, including a large companion called Charon. Pluto-Charon and some of the asteroid systems are sometimes considered to be double planets

They aren't considered planets.
Satelite is a general term for anything that orbits a planet, Moons are one type of satelite, but there are others that don't qualify as moons, such as the rings around Jupiter, Saturn, Uranus, and Neptune.

moons are satellites that circle around a main center(usually called a planet) some were made from the planet its self in pieces that broke away and established a orbit around the planet . some might be captured asteroids if the gravitational pull is strong enough.
some planets are gas giants that never became suns.
if a satellite is close in diameter to our planet. it may be called a planetoid.
quite confusing but i had nothing to do with setting up the naming system our ancestors did.

Moon have been reflected by the sun to give light in the dark night, that's why it's call satelites.

moons are satellites, not planets - they orbits round a planet.
I guess you are puzzled with artificial satellites which are launched by human beings. They have the name satellite as they orbits around the earth mimicking earth's natural satellite - "moon".
Other planets also have their natural satellites or moons .

A satellite is described as anything that orbits around another celestial body. Satellites are not limited to objects made by man.
