According to the International Astronomical Union, which sets definitions for planetary science, a dwarf planet is a celestial body that:
- Orbits the sun.
- Has enough mass to assume a nearly round shape.
- Has not cleared the neighborhood around its orbit.
- Is not a moon.
The main distinction between a dwarf planet and a planet is that planets have cleared the path around the sun while dwarf planets tend to orbit in zones of similar objects that can cross their path around the sun, such as the asteroid and Kuiper belts. Dwarf planets also are generally smaller than the planet Mercury.
The first five recognized dwarf planets are Ceres, Pluto, Eris, Makemake and Haumea. Scientists there may be dozens or even more than 100 dwarf planets awaiting discovery.
The IAU recognized Pluto's special place in our solar system by designating dwarf planets that orbit the sun beyond Neptune as plutoids. Eris, which orbits far beyond Neptune, is a plutoid while Ceres, which orbits in the main asteroid belt between Mars and Jupiter is a dwarf planet.

Is Pluto a moon or a planet?
no it's a dwarf planet I would think that it is a dwarf planet, but its moon, Sharon, is nearly as big as it, so some MAY argue that Sharon is a dwarf planet and Pluto is the moon, but considering Pluto is slightly bigger than Sharon, I would think that Sharon would orbit Pluto rather than Pluto orbiting Sharon.

How is a moon different from a dwarf planet?
Generally, a dwarf planet orbits only the sun, whereas a moon orbits a planet, which in turn orbits a sun.
How is a planet different from a dwarf planet and the moon?
A planet is bigger than a dwarf planet and the Moon. A planet revolves around the Sun directly in its own orbit, but so does a dwarf planet. However, the planet is the dominant object in its orbital region. A dwarf planet is not the dominant object. That's the important difference.
