Haumea was discovered in 2003 and became our fifth dwarf planet in 2008. Its shape and composition set it apart from other objects in the Kuiper belt, and it is one of the fastest rotating large objects in the solar system. Haumea is elongated in shape and is made up of a rocky interior covered by a thin icy crust.

Be mostly round. Dwarf planets like Pluto were defined as objects that orbit the Sun, and are nearly round, but have not been able to clear their orbit of debris. So far, the IAU has only recognized five dwarf planets. In order of distance from the Sun they are: Ceres, Pluto, Haumea, Makemake, and Eris. But the IAU says there may be many more ...
Apr 19, 2023 · Let’s visit the Solar System’s five official dwarf planets, starting from the one closest to the Sun and journeying outward. Ceres Color global view of Ceres: Oxo and Haulani craters This approximately true-color image was taken at 4:13 on May 4, 2015, as Dawn was surveying Ceres in its "Rotation Characterization 3" orbit 13,642 kilometers above the surface.
dwarf planet, body, other than a natural satellite (moon), that orbits the Sun and that is, for practical purposes, smaller than the planet Mercury yet large enough for its own gravity to have rounded its shape substantially. The International Astronomical Union (IAU) adopted this category of solar system bodies in August 2006, designating ...

- Pluto: The demoted former planet. Pluto was discovered by American Clyde Tombaugh in 1930, as part of a search for the mythical "Planet X" that was thought to be perturbing the orbit of Uranus.
- Eris: The troublemaker. Caltech astronomer Mike Brown led the team that discovered Eris in 2005. The find spurred the IAU to strip Pluto of its planethood and create the "dwarf planet" category a year later.
- Haumea: The oddball. Haumea, a Kuiper Belt denizen orbiting slightly beyond Pluto, was discovered by Brown and his team in late 2004. It's one of the weirdest objects in the solar system.
- Mysterious Makemake. Brown's team also discovered Makemake, spotting the dwarf planet in 2005. Astronomers aren't sure of Makemake's exact size, but the dwarf planet is thought to be about three-quarters as big as Pluto.
A dwarf planet is a small planetary-mass object that is in direct orbit around the Sun, massive enough to be gravitationally rounded, but insufficient to achieve orbital dominance like the eight classical planets of the Solar System. The prototypical dwarf planet is Pluto, which for decades was regarded as a planet before the "dwarf" concept ...

Dwarf Planet Facts. There are 5 officially recognised dwarf planets in our solar system, they are Ceres, Pluto, Haumea, Makemake and Eris. With the exception of Ceres, which is located in the asteroid belt, the other dwarf planets are found in the outer solar system. There are another 6 objects in our solar system that are almost certainly ...
