Dwarf planets are similar to the planets we know, but they are still different. Dwarf planets have enough mass to clump themselves in to an almost-round shape, just like planets. Dwarf planets also orbit around the Sun, just like other planets. But, their orbital path is not cleared of asteroids and space dust, so they have a very bumpy ride! The other planets have already cleared their orbital path millions of years ago and now have a smooth ride without crashing into asteroids and other debris. Dwarf planets are also located with lots of asteroids such as the Asteroid Belt and the outer parts of the Solar System. Dwarf planets are also smaller than regular planets! That is what dwarf planets are!
