• c. May 31: the planetoid 90377 Sedna is expected to reach its perihelion, its closest point to the Sun. It is expected to reach a distance of 76 AU, or 76 times the average distance Earth is from the Sun. Sedna has a highly elliptical orbit, thus it is difficult to locate —at its aphelion, it reaches a distance of about 942 AU. This date is subject to adjustment as Sedna's orbit is still being refined.
