As Sedna nears its perihelion in mid-2076, [6] [b] the Sun will appear merely as a very bright pinpoint in its sky, the G-type star too far away to be visible as a disc to the naked eye. [42] When first discovered, Sedna was thought to have an unusually long rotational period (20 to 50 days). [43]

One particularly distant body is 90377 Sedna, which was discovered in November 2003.It has an extremely eccentric orbit that takes it to an aphelion of 937 AU. [2] It takes over 10,000 years to orbit, and during the next 50 years it will slowly move closer to the Sun as it comes to perihelion at a distance of 76 AU from the Sun. [3] Sedna is the largest known sednoid, a class of objects that ...
Sedna is an open-source database management system that provides native storage for XML data. The distinctive design decisions employed in Sedna are (i) schema -based clustering storage strategy for XML data and (ii) memory management based on layered address space .
For comparison, Sedna has a barycentric semi-major axis of 506 AU and a period of 11,400 years. [12] Both (308933) 2006 SQ 372 and (87269) 2000 OO 67 take longer than Sedna and 2007 TG 422 to orbit the Sun using barycentric coordinates.
