New 5th Moon of Pluto Discovered --"Like Nested Russian Dolls"

A team of astronomers using the NASA/ESA Hubble Space Telescope has discovered a fifth moon orbiting the icy dwarf planet Pluto. Pluto’s new-found moon, visible as a speck of light in Hubble images, is estimated to be irregular in shape and between 10 and 25 kilometres across. It is in a 95 000 kilometre-diameter circular orbit around Pluto that is assumed to lie in the same plane as Pluto’s other known moons.
