The Dwarf Planets

Dwarf planet, body, other than a natural satellite (moon), that orbits the Sun and that is, for practical approach, it is smaller than the planet Mercury yet large enough for its own gravity to have orbicular its shape extensively. In August 2006, the International Astronomical Union (IAU) embrace this group of solar system bodies, nominate Pluto, the even more-distant object Eris, and the asteroid Ceres as the first members of this category. However major planets, these bodies are not enormous enough to have brush up smaller nearby bodies by its gravitational force; they thus decline to grow larger. The IAU shows their acceptance to authorize a process for deciding which other bodies currently known or to be exposed as dwarf planets. In June 2008 the IAU created a new category, plutoids, within the dwarf planet category. Plutoids are dwarf planets that are farther from the Sun than Neptune. All the dwarf planets excluding Ceres are plutoids; because of its location in the asteroid belt, Ceres does not come into it. For a consideration of the formal conditions laid out by the IAU for a body to be a dwarf planet.
Dwarf planets as 'plutoids'
Pluto, Eris, Haumea and Makemake are all known as "plutoids" however the asteroidal dwarf planetoid Ceres. A plutoid is a dwarf planet with an orbit outside that of Neptune. Plutoids are constantly referred to as "ice dwarfs" due to their pint-sized and cold outer temperatures.
The outer planets show testimony of synergy with plutoids. Triton, which is the largest moon of Neptune, is like a round up plutoid, and it is even conceivable that the odd tilt of Uranus on its axis is due to a bump with a plutoid. As well as to dwarf planets, there are probably hundreds of plutoid objects in the solar system that have yet to be given official status.
