Because of the problems with observing such a small object at such distances many details about Dysnomia are vague. Performance & security by Cloudflare. At its extremes it reaches 0.5 Au (e.g.
Dwarf Planet. , Evidence from 2019 suggests that Theia, the former planet that collided with Earth in the giant-impact hypothesis, may have originated in the outer Solar System rather than in the inner Solar System and that Earth's water originated on Theia, thus implying that Theia may have been a former dwarf planet from the Kuiper Belt.
It has an extremely fast (for a planet) rotation of once every 4 hours and this has pulled it into a ellipsoidal shape - rather like a squashed rugby (or American football) ball, spinning on its side.
Rather like Ceres before it, it has suffered because of the number of similar objects now discovered in the same region mean that it can no longer be thought of as one of the major planets. This is because determining whether a body is in hydrostatic equilibrium requires close observation by spacecraft. Ceres displays such planetary-geologic features as surface salt deposits and cryovolcanos, while Pluto has water-ice mountains drifting in nitrogen-ice glaciers, as well as an atmosphere. Images were acquired by Dawn at 04:13 UT May 4, 2015, at a distance of 13641 km. Unlike the other dwarf planets, Ceres is also an asteroid.
Haumea was discovered in 2004/5 with some doubt over who actually gets the credit for it.
Vesta, the next-most-massive body in the asteroid belt after Ceres, was once in hydrostatic equilibrium and is roughly spherical, deviating mainly because of massive impacts that formed the Rheasilvia and Veneneia craters after it solidified. (3) All other objects,3 except satellites, orbiting the Sun shall be referred to collectively as "Small Solar System Bodies.". The name and precise nature of this category were not specified but left for the IAU to establish at a later date; in the debate leading up to the resolution, the members of the category were variously referred to as plutons and plutonian objects but neither name was carried forward, perhaps due to objections from geologists that this would create confusion with their pluton.. At this point a body is as round as it is possible to be, given its rotation and tidal effects, and is an ellipsoid in shape.
• Alan Stern coined the term dwarf planet, analogous to the term dwarf star, as part of a three-fold classification of planets, and he and many of his colleagues continue to classify dwarf planets as a class of planets. The largest Moon is Charon (1200km diameter). For example, Pluto has three moons that circle it but there are several smaller objects that also occupy the space around Pluto. The diameter is thought to be somewhere between 150 and 650km.

The IAU's initial draft proposal included Charon, Eris, and Ceres in the list of planets. Those objects that have absolute magnitudes greater than +1, and so meet the criteria for the dwarf-planet naming committee of the IAU, are highlighted, as is Ceres, which has been accepted as a dwarf planet by the IAU since they first debated the concept, though it has not yet been demonstrated to meet the definition. Charon, a moon of Pluto that was proposed as a dwarf planet by the IAU in 2006, is included for comparison.
Apart from long-period comets and space probes, Eris and its moon are currently the most distant known objects in the Solar System. To help support the investigation, you can pull the corresponding error log from your web server and submit it our support team.
