How is a Dwarf Planet similar to and different from a Planet?
I know that there must be some physical characteristics requirement(most probably having something to do with mass of the body) that allow one to make the distinction. I heard that the Planet Pluto was demoted by scientist from wearing the mantle of Planet. But Mercury, the next smallest is sitll considered a planet, so if mass is the determinant what is it that Mercury has and Pluto lacks? This is just an intelligent guess, I am sure that your answer is in Wikipedia.
A Dwarf Planet is a body, like a planet. However, anything significantly smaller than Mercury is a dwarf planet. Some moons are larger than Mercury.
In addition to the 8 planets - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune - the solar system also contains several dwarf planets. Find out where they are and why they are so special. read more
