NASA’s Hubble Space Telescope has discovered a new moon orbiting the dwarf planet, Pluto. This new moon is much smaller than the others that were discovered in previous years.
“The new moon is the smallest moon yet discovered around Pluto. It has an estimated diameter of 8 to 21 miles (13 to 34 km). By comparison, Charon, Pluto’s largest moon, is 648 miles (1,043 km) across, and the other moons, Nix and Hydra are in the range of 20 to 70 miles in diameter (32 to 113 km).”
