Gravity. As the planet rotates it's mass holds it's moons within it's orbit. The larger the planet the stronger is its gravitational pull.
moon Actually, anything that orbits a planet is called a satellite. Natural examples are moons, but man-made ones are things like the telescopes sent up from earth.
A moon orbits around a planet, while a planet orbits around a star. Moons tend to have faster and smaller orbits compared to planets, which follow larger and slower orbits around the star. Additionally, moons' orbits are influenced by the gravitational pull of their host planet, whereas planets are not typically influenced by other celestial bodies in the same way.
Planet X is a hypothetical planet that has yet to be confirmed. Therefore until it is discovered, it will not have any moons.
A natural satellite (or moon), usually orbits a major planet.
Both asteroids and moons can be rocky. An asteroid orbits the Sun while a moon orbits a planet. Mars has two moons (Deimos and Phobos) that are most likely former asteroids.
A planet orbits a star. A moon orbits a planet or dwarf planet.
Moons don't orbit stars; they orbit planets. If it's a moon, then it orbits a planet. If it orbits a star, then it isn't a moon, it's a planet.

A planet and its moons are collectively referred to as a planetary system. The planet is the primary celestial body that orbits a star, while moons are natural satellites that orbit the planet.
A moon is an object that orbits a planet. A planet cannot orbit another planet.
Titan is one of Saturn's moons.
A moon, or perhaps many moons.
A moon orbits around a planet, while a planet orbits around a star. Moons tend to have faster and smaller orbits compared to planets, which follow larger and slower orbits around the star.

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.
The satellite Triton is on the planet Neptune. It is the largest of Neptune's moons. Neptune has 13 moons. It orbits in the opposite direction if its planet's rotation.
All the planets except Venus and Mercury have moons.
