All matter has a gravitational pull. Even you have a gravitational pull too. It is just that since your mass isn't quite as big as the Earth, your you can't see things moving towards you. When you jump, the Earth pulls you down. THat is cause the Earth is considerably bigger than you and you are attracted to the Earth. Some planets have more moons because of their mass. Since they are bigger and more massive, they pull much more stuff around them to orbit.

Do all planets have the same number of moons?
No, some planets like Mercury and Venus don't have any moons. Earth has one moon, Mars has two moons, and the outer planets have lots of moons. Jupiter has more than 60.
Astronomers have found all of the moons of the outer planets?
Its unlikely that all of the moons of the other planets have been found, but certainly all of the major moons have now been discovered. Some of Saturns named moons are only a few km across, so there are likely to be some more moons of this sort of size that have yet to be officially recognised.
Why do giant planets have many more moons than terrestrial planets?
Gas giants are larger and there for have a stronger gravitational pull. When the solar system was forming, the larger planets with greater gravitational pulls collected more satellites and therefore have more moons.
Can dwarf planets have moons?
Yes, and they do. Not all of them have confirmed moons but some do. Pluto, for example, has four known moons.
What are some similarities of the inner and outer planets?
Inner and outer planets have some things that are in common but there mostly way different. For instants they both orbit the sun. On the other hand the outer planets are made mostly by gas, that's why they are called the gas giants. The inner planets are mostly made by rock and dust. The inner planets are called Terrestrial planets and the outer planets are called Jovian planets. The inner planets are closer to the sun, have more density, they have less moons, there about the size of Earth, and they rotate slowly. The outer planets (Jovian Planets) are farther from the sun, they have less density, they have more moons, they are large, about the size of Jupiter, they rotate rapidly, and they have more mass. These planets are alike because they both orbit the sun.

Do inner planets have more moons than outer planets?
Yes, Jupiter and Saturn each of 60 some moons, while Uranus and Neptune have around twenty. The dwarf planet Pluto has three moons.

What orbits some planets?
moons
Is the earth the only planet with a moon or moons?
Within the Solar System, Earth is the only planet with one moon - The Moon.
Do other planet or moons might support life no or yes?
Yes,Other planets could scientists believed some life were on other planets and signs of life
How are other planets compared with earth?
some planets are bigger and some are smaller. some have different atmospheres. some of the planets are almost pure gas. some planets have as much as like 60 moons while ours only has one
Why do giant planets have many more moons than terrestrial planets?
Gas giants are larger and there for have a stronger gravitational pull. When the solar system was forming, the larger planets with greater gravitational pulls collected more satellites and therefore have more moons.
What planets in the galaxy have moons?
In our own solar system, Earth, Mars, Jupiter, Saturn, Uranus and Neptune have moons. Of the 300+ "exoplanets" that have been discovered (planets that orbit other stars) we would not expect to be able to detect moons from so far away. The probability that some of those planets will have moons is very great, however.
Why do the planets go round the sun and not the moon?
Because the moons are the ones revolvimg around the planets (only some planets have moons, not all). And besides, moons aren't in the center of the solar system. They're even smaller than the planets.
Can dwarf planets have moons?
Yes, and they do. Not all of them have confirmed moons but some do. Pluto, for example, has four known moons.
