Several planets in our solar system have moons. Here is a list of planets along with the number of known moons they have as of my knowledge
- Mercury: 0 moons
- Venus: 0 moons
- Earth: 1 moon (called the Moon)
- Mars: 2 moons (Phobos and Deimos)
- Jupiter: 79 known moons (including the four largest moons: Io, Europa, Ganymede, and Callisto)
- Saturn: 82 known moons (including the largest moon, Titan)
- Uranus: 27 known moons (including Miranda, Ariel, Umbriel, Titania, and Oberon)
- Neptune: 14 known moons (including Triton, which is the seventh-largest moon in the solar system)
- Pluto (dwarf planet): 5 known moons (including Charon, the largest moon)
It's worth noting that the number of known moons for each planet may change over time as new discoveries are made and our exploration of the solar system continues. Additionally, some planets have additional objects in their vicinity, such as asteroid-like bodies or small captured satellites, which are sometimes referred to as moonlets or irregular satellites.
