Created Wed Jan 22 22:19:50 2014 using Find_Orb
More info on this object can be found at http://nssdc.gsfc.nasa.gov/nmc/masterCatalog.do?sc=2007-004B. It has since been moved to the Moon, and (as of early 2014) is still orbiting it; you can click here for current information on this probe. It was launched with four other probes to explore the earth's magnetosphere. One of its companion objects, which has since also moved to a lunar orbit, has also been observed.
