A dwarf planet, as defined by the International Astronomical Union (IAU), is a celestial body orbiting a star that is massive enough to be spherical as a result of its own gravity but has not cleared its neighbouring region of planetesimals and is not a satellite.
In order from least to greatest in mean radius:Vesta (protoplanet)Pallas (protoplanet)Charon+ (dwarf planet)Orcus (dwarf planet)Quaoar (dwarf planet)Ceres (dwarf planet)Sedna (dwarf planet)"Snow White" [2007 OR10]* (dwarf planet)Haumea* (dwarf planet)Makemake (dwarf planet)Pluto+ (dwarf planet)Eris (dwarf planet)Mercury (terrestrial planet)Mars (terrestrial planet)Venus (terrestrial planet)Earth (terrestrial planet)Neptune (ice giant)Uranus (ice giant)Saturn (gas giant)Jupiter (gas giant)*There is a slight discrepancy as to how Haumea ought to be measured, due to its unusual shape. This makes it slightly unclear as to which is considered larger between Haumea and "Snow White."+Binary planet
---- Saturn is a planet, the only dwarf planet is pluto. ---- It's a gas giant!

No, Uranus is not a dwarf planet. It is classified as an ice giant planet in our solar system, along with Neptune. Uranus is the seventh planet from the Sun and is much larger than the dwarf planets such as Pluto.
Pluto was discovered in 1930 and dubbed the ninth planet. It was known as the ninth planet up until 2006, when it was reclassified as a dwarf planet. Now there are only eight officially recognised planets in our solar system, with an additional five dwarf planets and several more dwarf planet candidates.
Moons orbit planets. Planets (and dwarf planets) orbit stars.
It makes it spherical.
A dwarf planet is not considered a planet because it does not dominate its orbital path and cannot clear that path of debris.
Dwarf planets are not a special type of planet. A small planet is later classified a dwarf planet. The only characteristic that makes it a dwarf planet is the size. Your question should be why are some planets small?
Yes, Quaoar is considered a dwarf planet. It is located in the Kuiper Belt, beyond Neptune, and has not cleared its orbit of other debris. This makes it one of the criteria for being classified as a dwarf planet.
Pluto the dwarf planet is an example of of a dwarf planet.
Mercury is not a dwarf planet. It is a planet.
dwarf is a dwarf planet because it is to small to be in the solar system.,

Hiʻiaka is the larger, outer moon of the dwarf planet Haumea.It is NOT a dwarf planet.
Ceres is a dwarf planet. There is no such thing as a gas dwarf planet - Yet!
Quaoar is an official dwarf planet.
