IT IS NOT A PLANET!!
Sedna roams from 76 to 1000 times the Earth-Sun distance.
Sedna, officially known as 2003 VB12 by astronomers, was discovered while its highly elliptical (egg-shaped) orbit brings it closer to the Sun. The closest it gets (known as the perihelion, which will be later this century in the 2070s) is 76 AU, and the farthest away is 990 AU
90377 Sedna is a trans-Neptunian object, discovered by Michael Brown (Caltech), Chad Trujillo (Gemini Observatory) and David Rabinowitz (Yale University) on November 14, 2003. At the time of its discovery it was the most distant observed natural solar system body. Sedna may qualify as a dwarf planet pending the detailed definition of that category by the International Astronomical Union.
