Asteroid Sedna | Space Reference
WEBSedna is a dwarf planet whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified Sedna as potentially hazardous because its orbit does not bring it close to Earth. Sedna orbits the sun every 4,600,000 days (12,594.11 years), coming as close as 76.37 AU and reaching as far as 1006.83 AU from the sun.
