Sedna (minor-planet designation: 90377 Sedna) is a dwarf planet in the outermost reaches of the Solar System, orbiting the Sun far beyond the orbit of Neptune. Discovered in 2003, the frigid planetoid is one of the reddest known among Solar System bodies.
One particularly distant body is 90377 Sedna, which was discovered in November 2003.It has an extremely eccentric orbit that takes it to an aphelion of 937 AU. [2] It takes over 10,000 years to orbit, and during the next 50 years it will slowly move closer to the Sun as it comes to perihelion at a distance of 76 AU from the Sun. [3] Sedna is the largest known sednoid, a class of objects that ...
The first sentence of the article states directly "Sedna (minor-planet designation 90377 Sedna) is a dwarf planet " but the classification section states that the official classification body considers it to be a "scattered object", but also says that some consider it a new class of object, and that it is also expected to meet the requirements ...
Emery et al. suggest that Sedna, Quaoar, and Gonggong went through internal melting, differentiation, and chemical evolution like the larger dwarf planets, but that all smaller KBOs did not. [4] The question of current equilibrium was not addressed; nonetheless, it is not generally taken seriously despite being in the definition.
Sedna's orbit takes it far beyond even the Kuiper belt (30–50 AU), out to nearly 1,000 AU (Sun–Earth distance) Main article: Extreme trans-Neptunian object Among the extreme trans-Neptunian objects are three high-perihelion objects classified as sednoids : 90377 Sedna , 2012 VP 113 , and 541132 Leleākūhonua .
