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 ...

Dwarf planets in order from the Sun. As given in the above table, Ceres is the closest dwarf planet in our solar system and it is also IAU-defined. The IAU-defined farthest dwarf planet is Eris which is located in the scattered disc with a distance of around 67.78 AU from the sun. 1. Largest Dwarf Planet (Pluto)
Apr 19, 2023 · Dwarf planet Eris orbits an average of 68 times farther away from the Sun than Earth. At the farthest point in its orbit, its tenuous atmosphere may freeze and collapse onto the surface. When Eris reaches the closest point in its orbit to the Sun, the warmed frozen atmosphere may sublimate off the surface, turning from a solid directly into a gas.
Mar 29, 2024 · The closest dwarf planet to the Sun, and the only dwarf planet in the inner solar system, Ceres orbits the Sun from an average distance of 257 million miles (413 million kilometers) Ceres is about 2.8 times farther from the Sun than Earth.

There was much outrage and confusion in 2006 when Pluto lost its status as our solar system’s ninth planet. But we didn’t just lose a planet—we gained five dwarf planets! The term "dwarf planet" is defined by the International Astronomical Union (IAU) as "a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gra...
First is Pluto, the former planet. Discovered in 1930, it was named for the Roman god of the underworld. Its largest moon, Charon, is almost its equal in size and the two are often considered a double system. Telescopes have not yet been able to get a clear view of this faraway world, but the spacecraft New Horizons is scheduled to arrive there in ...
Eris was the troublemaker that led to Pluto’s reclassification. It was discovered in 2005 and, because it is close in size to Pluto, briefly considered the solar system’s tenth planet. After its discovery, astronomers were forced to reconsider the definition of "planet" entirely. Eris was named after the Greek goddess Eris, who started the Trojan w...
Unlike the other dwarf planets, Ceres is also an asteroid. The largest known asteroid in the asteroid belt, in fact, and the first to have been discovered. It was found in 1801. The name Ceres comes from the Roman grain goddess who was the patron goddess of Sicily, and with it began the tradition of naming main-belt asteroids after female character...
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. It was named for the Hawaiian god...
Makemake was the last of the dwarf planets to be discovered. Scientists found it shortly after Easter in 2005 and nicknamed it "Easterbunny." Its official name comes from the Rapa Nui fertility god. The Rapa Nui are the native people of Easter Island (you may know it from its giant stone statues), which brings the story full circle. Makemake has no...

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.
