The tiny, distant and frozen planet Pluto, for 30 years believed to have just one moon, has suddenly been found to have two more satellites, Reuters reported. Only discovered in 1930 because of its vast distance from Earth, Pluto has remained a largely enigmatic object ever since. Some three billion miles from the Sun, Pluto, the ninth planet, is the only one not yet to have been visited by a spacecraft. Its first known satellite Charon was not discovered until 1978. With a diameter of 1,200 km, it is half that of Pluto -- abnormally large for a moon in relation to its primary. But now, using images from the Hubble Space Telescope, scientists from Johns Hopkins University, Southwest Research Institute and the Massachussetts Institute of Technology say they have found two more tiny orbiting satellites, P1 and P2. Both are travelling outside the orbit of Charon and are tiny by comparison, the scientists wrote in the journal Nature. --More 21 21 Local Time 18 21 GMT
