It was calculated in 2011 that a flyby mission to Sedna could take 24.48 years using a Jupiter gravity assist, based on launch dates of 6 May 2033 or 23 June 2046. Sedna would be either 77.27 or 76.43 AU from the Sun when the spacecraft arrives near the end of 2057 or 2070, respectively. [ 107 ]

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 ...
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 ...

Sedna is a trans-Neptunian object with the asteroid number 90377. It was discovered on November 14, 2003 by astronomers Michael Brown , Chad Trujillo , and David Rabinowitz . Sedna is currently 88 Astronomical units (AU) from the Sun , which is three times the distance between Neptune and the Sun. Sedna's orbit is an ellipse and its aphelion is ...
