Sedna - 2076?

In 2076, around May 31, the planetoid 90377 Sedna is expected to reach its perihelion, in other words, reach the closest it can get, orbit-wise, to the Sun. It is expected to reach a distance of 76 AU, or 76 times the distance Earth is from the Sun. Sedna has a highly elliptical orbit, thus it is difficulty to locate —at its aphelion, it reaches about 942 AU. This date is subject to adjustment as Sedna's orbit is still being refined.
