The two that have been identified and named are Eris and Sedna, although Pluto arguably belongs in the "Kuiper belt" category as well. However, there are certainly hundreds, more likely millions of similar objects that are still just a little too far away to be detected by our terrestrial telescopes.
Edit: I think the correct answer is : Haumea and Makemake.
Also I would definitely say Pluto is in the Kuiper Belt. So that's three Dwarf Planets in the Kuiper Belt.
Eris is a "Scattered Disc Object", but some astronomers consider it as a Kuiper
Belt Object too.
Sedna, as far as I know, has not yet been classified as a Dwarf Planet.
Pluto, Haumea, and Makemake are in the Kuiper belt.
Pluto and Eris
There are no planets in the Kuiper Belt. Anything in the Kuiper belt pretty much is not a planet by definition (KBOs do sometimes cross the orbit of Neptune, though).
Pluto is considered to be two different things. 1. Pluto is a dwarf planet. It is in hydrostatic equilibrium (round) and it orbits the sun, but it has not cleared its neighborhood of debris. What's its neighborhood? The Kuiper belt, a collection of icy objects similar to comets that somewhat resembles the asteroid belt. This leads to its second classification. 2. Pluto is a Kuiper Belt Object (KBO). Specifically, it's classified as a plutino - an object within a certain zone of the Kuiper Belt.
The current list of "dwarf planets" (round bodies that orbit the Sun independently) includes, in order of their orbital distance :Ceres (950 km in diameter and 1/3 of the total mass of the asteroid belt)Pluto (2390 km in diameter and formerly the 9th solar planet)Haumea (ellipsoid Kuiper Belt object about 1/3 Pluto's mass)Makemake (about 1800 km in diameter and a bit farther out than Haumea)Eris (at 2500 km in diameter and 1.27 the mass of Pluto, the largest discovered Kuiper object. With Dysnomia, its moon, it orbits the Sun once in 557 years.)Candidates for dwarf planet status include Sedna, pending verification of its mass and shape. (Sedna's closest approach to the Sun is barely within the Kuiper Belt, and its orbit may extend to nearly 1000 AU, into the Oort Cloud of comets.) Other Kuiper Belt bodies include Quaoar, Orcus, and Varuna. Pluto's moon Charon, and the large asteroids Vesta, Pallas, and Hygiea are also listed as potential candidates for dwarf planet status.The Four dwaf plants are PLui
Inner and outer. Planets inside the Asteroid Belt including Mercury, Venus, Earth, and Mars. And the planets outside the Asteroid Belt; Jupiter, Saturn, Uranus, Neptune, and Dwarf Pluto.
Pluto and Eris
There are no planets in the Kuiper Belt. Anything in the Kuiper belt pretty much is not a planet by definition (KBOs do sometimes cross the orbit of Neptune, though).
There are millions of them, ranging from the main eight planets, several further dwarf planets, comets, asteroids, kuiper belt objects and meteoroids. All in orbit around our sun.
As far as we know Haumea in the Kuiper belt has two moons, Hi'aka and Namaka.
There are very few "facts" about the Kuiper Belt; the only space probes ever to get that far were the two Voyager probes, and they weren't equipped to make any meaningful measurements of the small bodies that we expect to find there. So most of what we THINK we know are based on theories, or outright guesses. What we DO KNOW: There are three "dwarf planets" in the area of the Kuiper Belt, named Eris, Sedna, and Makemake.
So far, we have identified five "dwarf planets"; one in the asteroid belt (Ceres), and four in or near the Kuiper Belt. (Pluto is at least close to the Kuiper Belt.) We sort-of-expect to find more object which may, more or less, fit the description of "dwarf planet", but we won't really know until we get out there. In addition, there are two more asteroids (Pallas and Vesta) that perhaps ought to be re-classified as dwarf planets.
There isn't much difference except Pluto has a very low mass and is considered a "Dwarf Planet" and part of the Kuiper Belt. The Kuiper Belt is a collection of around 70,000 objects very similar to Pluto. Rules for being a Planet are: 1. Orbits around the Sun 2. Has sufficient mass to assume a nearly round shape 3. Has cleared the neighborhood (is gravitationally dominant) around its orbit Dwarf Planets only meet the first two requirements.
Mercury and Venus are the only two major planets in our solar system without moons. They are the two planets closer to the Sun than Earth.Two of the five dwarf planets have no known moons : the asteroid Ceres and the Kuiper Belt object Makemake.Neither Mercury nor Venus have any moons.

Ceres.... Is located in the asteroid belt and is considered a dwarf planet because of its size! Eris.... Is located in the kuiper belt and is also so tiny that it can not be classed as a planet Pluto.... Is located in the kuiper belt but does not orbit or is orbitted by Eris . Pluto was classed as a dwarf planet in 2006 when they realised it was so small to be classed as a planet! By the way I am 11 years old and hope to become can astomener when I am older I am about to leave primary school but I read much more than picture books! Do you think I could have a carrer in space research and astromany?
