Why is Pluto no longer a planet?

According to the IAU, Pluto is technically a “dwarf planet,” because it has not “cleared its neighboring region of other objects.” This means that Pluto still has lots of asteroids and other space rocks along its flight path, rather than having absorbed them over time, like the larger planets have done.

Can a dwarf planet have a moon?

Pluto and some other dwarf planets, as well as many asteroids, also have small moons. Saturn and Jupiter have the most moons, with dozens orbiting each of the two giant planets.

Can moons have moon?

Yes, in theory, moons can have moons. The region of space around a satellite where a sub-satellite can exist is called the Hill sphere. Outside the Hill sphere, a sub-satellite would be lost from its orbit about the satellite. An easy example is the Sun-Earth-Moon system.
