An object now thought to be smaller than Pluto, was, at the time of its discovery was thought to be the biggest so far, was discovered in a reanalysis in 2005; it was named Eris. Eris * Another minor planet that was discovered in November 2003 but not announced until March 2004 is Sedna. Sedna * A new dwarf planet, 2005 FY9 (Makemake), was discovered on March 31, 2005, by a team led by Mike Brown of the California Institute of Technology. It became the fourth dwarf planet and third plutiod, officially in July 2008. Makemake * Another recent dwarf planet that been recently named in 2008 is Haumea, discovered by José Oritiz and Micheal Brown on 28th December 2004. Haumea * Ceres is the smallest dwarf planet identified. It is the only dwarf planet located within the asteroid belt and was discovered by Giuseppe Piazzi. It is named after the Roman goddess Ceres, the goddess of growing plants, harvests, and motherly love. It has a diameter about 950 km and is the largest body in the asteroid belt.

- The term dwarf planet was adopted in 2006 as part of a three-way categorization of bodies orbiting the Sun, brought about by an increase in discoveries of trans-Neptunian objects that rivaled Pluto in size, and finally precipitated by the discovery of an even larger object, Eris. This classification states that bodies large enough to have cleared the neighbourhood of their orbit are defined as planets, while those that are not massive enough to be rounded by their own gravity are defined as small solar system bodies. Dwarf planets come in between. The definition officially adopted by the IAU in 2006 has been both praised and criticized, and remains disputed by some scientists. The IAU currently recognizes five dwarf planets—Ceres, Pluto, Haumea, Makemake, and Eris. However, only two of these bodies, Ceres and Pluto, have been observed in enough detail to demonstrate that they fit the definition. Eris has been accepted as a dwarf planet because it is more massive than Pluto, but this made the mass of Pluto the cut-off point for trans-Neptunian dwarf planets (plutoids). The IAU subsequently decided that unnamed trans-Neptunian objects with an absolute magnitude less than +1 (and hence a mathematically-delimited minimum diameter of 838 km) are to be named under the assumption that they are dwarf planets. The only two such objects known at the time, Makemake and Haumea, went through this naming procedure and were then immediately declared to be dwarf planets. It is suspected that at least another 40 known objects in the Solar System are dwarf planets, and estimates are that up to 200 dwarf planets may be found when the entire region known as the Kuiper belt is explored, and that the number might be as high as 2000 when objects scattered outside the Kuiper belt are considered. The classification of bodies in other planetary systems with the characteristics of dwarf planets has not been addressed, although if they were detectable they would not be considered planets.

(3) All other objects3, except satellites, orbiting the Sun shall be referred to collectively as “Small Solar System Bodies.” Footnotes: 1 The eight planets are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. 2 An IAU process will be established to assign borderline objects either dwarf planet or other status. 3 These currently include most of the Solar System asteroids, most Trans-Neptunian Objects (TNOs), comets, and other small bodies.
- A dwarf planet is a body found in a star system with sufficient mass to make it spheroid, but with insufficient effect on other bodies in it's orbit to clear the neighbourhood of other bodies. Bodies which can clear the neighbour are known as planets, while planetoids are another small planet like body comparable to dwarf planets. The ninth planet in the Sol system, Pluto, was classified as a dwarf planet in 2006. For over three hundred years to follow, its classification switched between planet and dwarf planet ten or more times. Pluto had once more been reclassified as a planet shortly before it was absorbed and destroyed by a Borg cube in 2380. (TNG novel: Before Dishonor)
- According to a recent Gallup poll, 9 out of 10 astronomers would prefer meeting a dwarf planet at a party to a regular planet. Currently, fake property deeds to dwarf planets sell for twice as much as land on the Moon and on Earth-sized planets, and three or four times as much as property on gaseous planets such as Uranus.
