Saturn, a planet 95 times more massive than Earth, has 62 moons, but only thirteen of them have diameters larger than 50 kilometres.
Saturn's moons are small compared to it's massive size, but here, four of Saturn's moons are visible here alongside the ringed planet. Two of these -- Janus and Epimetheus -- are so small, they're almost impossible to see here.
This week, NASA's Saturn orbserver Cassini returned incredible new views of the ringed planet's impressive moons, including the orbiter's closest-ever pass just 46 miles from Enceladus.
Mimas, 246 miles across, appears as a bright dot below the rings just to the right of the center of the image. Enceladus, 313 miles across, is visible below the rings on the far right of the image. Janus is 111 miles across, and can just barely be discerned as a tiny speck past Enceladus on the right edge of the image. Epimetheus, just 70 miles across, is likewise tiny, and can be detected on the extreme left of the image above the rings.
