Another perspective on size...

Mimas is the closest major moon to Saturn, about half the distance of the Earth to its Moon. Here, Bonestell's image takes on a surpassing accuracy: the 30 degree tilt and super thin looking rings. Remember, he did this over thirty years before anyone saw Saturn or Mimas this close.

Happily, astronauts are running around the surface here, too. Can you pinpoint all five?
