8bitfuture:Image: Quadruple moons transiting Saturn.The giant orange moon Titan, at the top right is larger than the planet Mercury, and the second largest moon in the solar system after Jupiter’s moon Ganymede. Titan is the only moon in our solar system known to have a dense atmosphere, and the only place other than Earth where stable bodies of surface liquid have been found.Three icy moons are also visible, with Enceladus and Dione at the left and Mimas on the far right. This picture was taken with Hubble’s Wide Field Planetary Camera 2 on 24 February 2009, when Saturn was at a distance of roughly 1.25 billion kilometres from Earth. -- source link
