Fact of the Day: Ganymede

The biggest moon in the solar system is Ganymede. It's one of Jupiter's moons, and was discovered by Galileo Galilei in 1610. It's bigger than Pluto and Mercury, and it's slightly smaller than the planet Mars.

I'm very fascinated by astronomy. It's mind blowing when you think about just how many planets and moons there are in the universe.

No wonder Pluto got the shaft, can't even beat a moon lol

I wonder if Ganymede will ever be colonized. But it's probably too cold and Jupiter's gravity may make things worse..

Jupiter and Ganymede were same-sex lovers and an inspiration to gay men for centuries afterwards who had to live in times of oppression.
