SUMMARY: A new object has been discovered in the Solar System; it's nearly as large as Pluto, but 13 billion kilometres away. Tentatively named Sedna, the Inuit goddess of the Sea, it's approximately 1,700 km in diameter, which makes it the largest Solar System object found since Pluto was located in 1930. Sedna is located in the Kuiper Belt, and follows a highly ecliptic orbit that takes 10,500 years to complete. The object was first discovered using the Gemini Observatory in Hawaii, and then confirmed with several other instruments, including the Spitzer Space Telescope.
