Pluto is a dwarf planet orbiting the Sun. It is yet to be visited by a space probe, however, the New Horizons spacecraft is currently on its way to a rendezvous in the year 2015. Previously classified as a planet, debate continues as to what its classification should be. This image was produced by mapping brightness changes as Pluto was occulted by its moon Charon.
