Dwarf planets can have moons. Here's why:

* Definition of a Dwarf Planet: A dwarf planet is a celestial body that orbits the Sun, is massive enough for its own gravity to pull it into a roughly round shape, but has not cleared its neighborhood of other objects.

* Moons are Satellites: Moons are natural satellites that orbit planets or dwarf planets.

* Examples: Several dwarf planets have moons, including:

* Pluto has five moons (Charon, Styx, Nix, Kerberos, and Hydra).

* Eris has one moon (Dysnomia).

* Haumea has two moons (Hiʻiaka and Namaka).

The definition of a dwarf planet focuses on its relationship to other objects in its orbital path, not on its ability to host moons.
