In November 2003 the known solar system grew significantly larger with the discovery of a new object, Sedna, 90 astronomical units from the Sun. (1 AU = 150 × 10⁶ km = 93 × 10⁶ mi, the average distance from the Earth to the Sun.) For comparison, Jupiter orbits 5 AU and Neptune 30 AU from the Sun. Objects in the Kuiper Belt, discovered beginning in 1992, orbit beyond Neptune at typical distances of around 40 AU, and are likely to be the closest relatives to Sedna.
