The inner planets of our solar system are Mercury, Venus, Earth, and Mars. Of these, only Earth and Mars have moons.

Here's a breakdown:

* Mercury and Venus have no moons.

* Earth has one moon, often simply referred to as "the Moon".

* Mars has two moons, Phobos and Deimos.

It's important to note that there are many other celestial bodies in our solar system, including dwarf planets and asteroids, that also have moons.
