How many moons does the sun have?

The sun has zero moons. A moon is a natural satellite of a planet, a dwarf planet, or even an asteroid. The sun is not one of those items. The sun is a star, and stars do not have moons; however, stars do have natural satellites. The natural satellites of a star are called planets, dwarf planets, asteroids, and/or comets. Our sun has eight planets that revolve around it. They are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Most of those planets have at least one moon in orbit; however, Mercury and Venus do not have any moons. In addition to those 8 planets, our solar system currently has 5 dwarf planets. While Jupiter and Saturn do have many more moons than the other planets, the size of the planet doesn't directly relate to the number of moons that a planet has. Earth is larger than Mars, yet Mars has twice as many moons as Earth. Pluto, as a dwarf planet, currently has five moons.
