On August 24, 2006 the International Astronomical Union adopted fixed definitions for various objects in the Solar System.
“Snow White,” otherwise known as 2007 OR10, is a dwarf planet about 13 billion kilometers from the Sun. Its orbit, canted by almost 31 degrees to the plane of the ecliptic, is so large that it was closest to the Sun in 1856 and will not reach its farthest point until 2130, taking more than 550 years to revolve.
Snow White joins many other icy worlds so far from the Sun that it would be hard to pick out that luminary from the star field. It is in a similar orbit with its sister dwarf Eris (2003 UB313) within a region occupied by so-called “Trans-Neptunian Objects” (TNO) or “Kuiper Belt Objects (KBO).”
