Description The artist's rendition shows the newly discovered planet-like object, dubbed "Sedna," in relation to other bodies in the Solar System, including Earth and its Moon, Pluto, and Quaoar, a planetoid beyond Pluto that was until now the largest known object beyond Pluto. The diameter of Sedna is slightly smaller than Pluto's but likely somewhat larger than Quaoar.

description The small dot moving slightly off to the left of center in this image is newly-discovered Kuiper Belt object 2004 DW. 2004 DW was found in images taken Feb 17, 2004 (nearly 74 years to the day after Pluto was discovered) by Mike Brown (Caltech), Chad Trujillo (Gemini Observatory) and David Rabinowitz (Yale). They are the same people who found Quaoar in the summer of 2002. 2004 DW is one of the largest Kuiper Belt objects currently known. Initial indications are that it may be over half the diameter of Pluto, larger than Quaoar, and 2.4 billion kilometers (1.5 billion miles) further away than Pluto.

description This artist's conception of newly-discovered object 'Quaoar' - orbiting our Sun far beyond Pluto - shows how the tiny object compares to the size of North America. It is the largest object discovered in our solar system since Pluto was found in 1930.
