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. [ 16 ]
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 ...
Hubble Space Telescope image of Sedna 90377 Sedna is a trans-Neptunian object currently about three times as far from the Sun as Neptune . For the majority of its orbit it is the most distant known object in the Solar System other than long-period comets .
These four panels show the location of trans-Neptunian object 90377 Sedna, which lies in the farthest reaches of the Solar System. [1] Each panel, moving clockwise from the upper left, successively zooms out to place Sedna in context. The first panel shows the orbits of the inner planets and Jupiter; and the asteroid belt.
90377 Sedna, a large trans-Neptunian object, had the provisional designation 2003 VB 12, meaning it was identified in the first half of November 2003 (as indicated by the letter "V"), and that it was the 302nd object identified during that time, as 12 cycles of 25 letters give 300, and the letter "B" is the second position in the current cycle.
90377 Sedna is a trans-Neptunian object currently about three times as far from the Sun as Neptune. For the majority of its orbit it is the most distant known object in the Solar System other than long-period comets .
