Sedna Discovery
Sedna was discovered on November 14, 2003 by a CalTech team, using the 48-inch Samuel Oschin Telescope at Palomar Observatory. The object lies more than 8 billion miles from the Earth, making it the most distant object ever observed in the solar system. Its official IAU provisional designation was minor planet 2003 VB12, but as of September 28, 2004 it officially became known as Sedna after the Inuit goddess of arctic sea life.
