The process of planet growth from a solar nebular is a very chaotic one. The process of moon formation (or preservation in planetary orbits) is one of chance. Some planets will have no moons others will have many moons. However it is likely that the innermost planets will have the smallest number.
The Moon has no natural satellites of its own. In theory it could (as planets have their own moons), but it is unlikely due to the precise orbital requirements. Most possible scenarios do not create stable orbits.
Most moons orbit their planet the same way the planet rotates. One of Neptune's moons is very different. That moon goes in the opposite direction of Neptune's rotation.
an exomoon is a natural satellite which orbits around an exoplanet, a planet which orbits around another star besides our sun. no exomoons have yet been discovered because they are too small to detectable by current technology. however, there existence is very plausible, because many moons occur in our solar system. they can be similar to our moons, lifeless and cold, asteroid sized to ganymedian size, but also can be as large as Earth, can have a sustainable atmosphere, possible occurring in the habitable zone, and possibly habitable, even more common than a habitable planet like our own.
8 of Jupiter's 63+ moons are large and fairly spherical, indicating that they may have formed around the planet during the creation of the solar system. Most of the others are in very irregular orbits that suggest they are asteroids captured by Jupiter's gravity (especially from the asteroid belt between Mars and Jupiter).

Mercury. It is the closest planet to the sun and so orbits at the fastest speed and in the shortest time, just 88 days. Venus also has no moons and orbits very quickly, since it is only the second planet out. Not as quickly as mercury though.

Saturn's rings are made up of loads of rocks, particles, dust and ice lumps that are all in independent orbits around the planet. They could be broken up, and have been, by some of the moons that are also in orbit around the planet. The gravitational effects of these moons can make the gaps between the rings. To be totally broken up, a very large object would have to come into play to upset the orbits of the ring material. Such an event would be very rare.
Mercury has no moons and no atmosphere. Venus has an atmosphere but no moons. Mercury probably has no moons and no atmosphere because it is very close to the sun.
Mars has two very tiny moons. Jupiter and Saturn also have lots of small moons, but they also have lots of big moons.
The Moon has no natural satellites of its own. In theory it could (as planets have their own moons), but it is unlikely due to the precise orbital requirements. Most possible scenarios do not create stable orbits.
A moon is a satellite that orbits a planet. So the Moon (our moon) is not a planet but a moon.It is worth noting that, in our solar system there are bigger moons; but the Moon is the largest moon in proportion to the size of the planet. As a result, it has a more significant gravitational effect upon the Earth than do most moons. Of course, the moon governs the tides; but also it helps to stop rotational irregularities of the Earth from getting out of hand; and so the moon has been a very fortunate and calming influence for our planet.
mars is a very unique planet because it has 2 moons!
The planet Saturn has 53 named moons (not only 23 moons), and another nine which are still being studied.Many of the moons are very small: 33 are less than 10 km in diameter and 13 moons are less than 50 km.Many of the moons are named after Titans, giants, or minor Greek or Roman gods.Some of Saturn's moons are very large; the moon Titan is bigger than the planet Mercury.
Most moons orbit their planet the same way the planet rotates. One of Neptune's moons is very different. That moon goes in the opposite direction of Neptune's rotation.
they are called Phobos and demos.both are irregular satellites,have a very low gravitational pull and orbit mars very fast. they must have been asteroids before have being caught by mars's gravitational pull
