Jupiter's moon Ganymede is bigger than Mercury
HERE’S THE INTERESTING PART
Nothing screams inadequacy like being outclassed by someone else's moon. This massive Jovian satellite is so incredibly huge that if it were orbiting the sun directly, it would easily be classified as a full-fledged rocky planet. It possesses its own internal magnetic field and a beautifully complex surface, making the actual planet Mercury look like a pathetic, scorched little afterthought.
One discovery leads to another.
