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.
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.
Yes. Every physical object has physical properties. Mercury has a heavily cratered silicate crust, a large iron-nickel core, and very little atmosphere.

Mars has two very tiny moons. Jupiter and Saturn also have lots of small moons, but they also have lots of big moons.
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.

That would be Mercury. Venus also has no moons, but does not move as fast as 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.

This tells you that, because Mercury is very cratered, it must have no protection against the asteroids coming in. So, it is basically telling you that Mercury has a very thin atmosphere
There is no major planet in the Solar System with four moons. Jupiter has at least 67, Saturn has at least 62, Uranus has 27 known moons, and Neptune has 14. Among the inner planets, Mars has two small moons and the Earth has one large Moon. The dwarf planet Pluto has 5 moons. One (Charon) is half as large as Pluto and the other four are very small. If Pluto and Charon were considered co-planets, they would be said to have 4 moons.
