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 ...
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, 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 ...

- Dwarf planets of the solar system. The International Astronomical Union defines a planet as being in orbit around the sun, has enough gravity to pull its mass into a rounded shape (hydrostatic equilibrium), and has cleared its orbit of other, smaller objects.
- Ceres. Ceres is the earliest known and smallest of the current category of dwarf planets. Sicilian astronomer Giuseppe Piazzi discovered Ceres in 1801 based on the prediction that the gap between Mars and Jupiter contained a missing planet.
- Pluto. Pluto is the most well known of the dwarf planets. Since its discovery in 1930 and until 2006, it had been classified as the ninth planet from the sun.
- Eris. When it was first discovered, Eris was thought to be the largest of the dwarf planets, with a mass 27 percent larger than that of Pluto and a diameter of approximately 1,400 to 1,500 miles (2,300 to 2,400 km).
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.

When Pluto was discovered in 1930, it was called the ninth planet in our solar system, but its status as a fully fledged planet came into question in the 1990s. Pluto was officially reclassified as a dwarf planet in 2006. The best-known dwarf planet, Pluto is also the largest in size and the second largest in mass. Pluto has five moons.
