Hubble Hunts Down Binary Objects at the Fringe of Our Solar System

NASA's Hubble Space Telescope snapped pictures of a double system of icy bodies in the Kuiper Belt. This composite picture shows the apparent orbit of one member of the pair. In reality, the objects, called 1998 WW31, revolve around a common center of gravity, like a pair of...

Artist's View of Kuiper Belt Object 1998 WW31

This is an artist's view of a Kuiper Belt binary object, called 1998 WW31. These icy bodies orbit each other at the fringe of our solar system. The illustration depicts one member of the duo in the foreground; its companion - the dark, round object - is in the background. The...
