Moon #5 For Pluto

A team of scientists using the Hubble Space Telescope has now discovered another tiny moon belonging to Pluto. This mini-moon is estimated to be up to 15 miles across, smaller than the one that scientists spotted last year, which is up to 21 miles wide. The dwarf planet's largest moon, Charon, is about 650 miles across. Pluto's known moon count is now five. Until the newly found moon gets a name, though, it will be known as P5.
