2004 DW is a newly discovered Kuiper belt object, 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). We 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.
