Scientists analysing images from the Hubble Space Telescope have discovered another moon circling the dwarf planet, Pluto. Named P5, the fifth moon is 9 to 24 km in diameter. The find adds evidence to the theory that Pluto’s moons were formed during a collision with another Kuiper Belt object. Scientists will get a better look at Pluto during a July 2015 flyby of Nasa’s New Horizons spacecraft. – Joe Pappalardo
