New moons discovered around Jupiter
As of 1 June 2011, the count of known moons orbiting Jupiter has increased from 63 to 65. The new moons, designated S/2010 J1 and S/2010 J2 are really tiny at 2km and 1km across respectively. They also have irregular orbits, moving the wrong way around Jupiter at steep angles, indicating that they were not part of Jupiter’s original set of satellites, but comets or asteroids that had been captured by Jupiter’s immense gravity. Any bets on when the next one will be found?
