Pluto may have two more moons than previously thought following investigations by the high-powered Hubble Space Telescope. Up until now, Pluto’s only known moon was Charon, which scientists discovered in 1978. Recent studies have spotted what could be two other moons. They’re a lot smaller than Charon and appear to be orbiting the planet at a much further distance. Scientists will take a closer look, then decide if they’ll name the moons.
