Summary
Description Pluto and its five moons.jpg |
English:
This discovery image, taken by the NASA/ESA Hubble Space Telescope, shows five moons orbiting the distant, icy dwarf planet Pluto. The darker stripe in the centre of the image is because the picture is constructed from a long exposure designed to capture the comparatively faint satellites of Nix, Hydra, Kerberos and Styx, and a shorter exposure to capture Pluto and Charon, which are much brighter.
Kerberos has an estimated diameter of 13 to 34 kilometres, and Styx is thought to be irregular in shape and 10 to 25 kilometres across.
