Eclipse
An eclipse, possibly.

A natural body that rotates around a planet is a satellite, as in a moon. Man made satellites (artificial satellites) are made mostly of metal and rotate around earth looking at weather patterns or orbiting other planets for information. When they say Neptune has eleven satellites, they mean moons orbiting the planet, not man made ones. There doesn't have to be anyone there for there to be satellites of both kinds there.
The amount of substance of a planet is measured in kilograms, a unit of mass. In this sense, there is no difference between one planet and another. It doesn't make much sense to speak about the "weight" of a planet, but you can measure the attraction between a planet and another object in units of force, i.e., in Newtons.
Another word for a meridian is a hemisphere. This is due to the fact that both of those words describe an imaginary line which divides the planet into sections.
just think the universe goes on forever. dont you think the probability is pretty high?

Eclipse
A satellite is an object that orbits a planet. The Sun is a star so it does not have satellites. Actually a satellite is anything that orbits another. So the planets and asteriods are the sun's satellites.
you can see a shadow on the planet and its so cool
The effect of a planet or satellite casting a shadow on another is called an eclipse. We see this most often when the earth goes between the moon and the sun. We have solar eclipses where the moon goes between the earth and sun also.

A moon or satellite. what are the natural satellites which revolve around 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.
a planetary satellite is any object that orbits a planet
By definition planets orbit a star and satellites orbit a planet. Therefore there are no satellite planets.
There are two types of satellites, Genuine Satellites, which are any body that orbit a planet. For instance, our moon is a satellite of the earth, and there are artificial satellites which are man made objects that orbit a planet. These range from few tens of millions, to few hundred millions.
If the Moon is to a satellite, then Earth is to a planet. The Moon is a natural satellite orbiting Earth, just like artificial satellites orbit Earth. Similarly, planets are natural satellites orbiting stars, like Earth orbits the Sun.
