SUMMARY: Astronomers recently announced the discovery of Sedna, a nearly Pluto-sized object on a 12,500 year-long orbit around the Sun. New computer simulations from the Southwest Research Institute demonstrate that Sedna could formed out past the orbit of Pluto, instead of being created closer to the Sun, and then ejected by the gravity of the gas giants. If this happened, it would mean that the zone of planetary formation in our Solar System could extend much further than previously believed, and there could be other objects like Sedna lurking in outer reaches.
