Pluto System Hubble

Caption

This composite image from the Hubble Space Telescope shows Pluto and its largest moon, Charon, at the center. Pluto's four smaller moons orbit this 'binary planet' and can be seen to the right and left. The smaller moons must be imaged with 1000 times longer exposure times because they are far dimmer than Pluto and Charon.
