The Hubble Space Telescope has discovered a fifth moon circling the dwarf planet Pluto.
The new moon, visible as a speck of light in Hubble images, is estimated to be irregular in shape and between 10km and 25km across.

Pluto's largest moon, Charon, was discovered in 1978. Hubble observations in 2006 uncovered two additional small moons, Nix and Hydra. In 2011, another moon, known as P4, was found by Hubble.

The new moon - known only as P5 - could help shed light on how the Pluto system formed and evolved.
