Moons are the natural satellites of a planet and these celestial bodies orbit around the planet. The name of Earth's natural satellite is Moon. Similarly, many of the other planets of our solar system also have moon/s. Here is a list of number of moons of each planet in our solar system:

Mercury: 0 moons

Venus: 0 moons 

Earth: 1 moon

Mars: 2 moons

Jupiter: 67 moons* (including 17 provisional moons)

Saturn: 62 moons* (including 9 provisional moons)

Uranus: 27 moons 

Neptune: 14 moons* (including 1 provisional moon)

Thus, Jupiter and Saturn have the largest number of moons, as compared to other planets of our solar system. 

The 4 most famous moons of Jupiter are known as Io, Ganymede, Callisto and Europa. The most famous moon of Saturn is known as Titan. 

Note that the number of moons of each planet may change (in future) depending upon the observation of newer celestial bodies with better technology in the future. 

Hope this helps.

Jupiter and Saturn are the two planets with the most moons.

A moon is a natural satellite that orbits a planet. Since the Sun is classified as a star, it does not have any moons. However, the Sun does have other satellites that orbit it, such as planets, asteroids, comets, and planetoids.

There are nine planets within our Solar System. Venus and Mercury are the only planets that do not have moons. All other planets in our Solar System do have moons. According to NASA, Earth has one moon; Mars has two moons; Jupiter has fifty moons; Saturn has fifty-three moons; Uranus has twenty-seven moons; and Neptune has thirteen moons. Please note that the number of moons per planet changes over time as new discoveries are made. Even current resources depict different numbers of moons per planet.
