Ganymede

NASA. Hubble.

Ganymede is the largest moon in our solar system. It is one of Jupiter's sixty four moons. At 5288 km at the equator, it is three times the size of our Moon. It would even be classified as a planet if it were to break free of the gravitational pull of Jupiter. It is actually larger than Mercury and Pluto, the latter being down graded to a planetoid and then being upgraded to dwarf planet. Only we humans could have an argument about what weight class to put a fucking planet in. 
The surface is mostly made up of rock and ice, at times being up to 800 km thick. How can this be, you ask? I do not know but that is a lot of rock and ice. I think it would be better on our Moon. Why do we call our moon The Moon and then all other chunks of rock floating around planets are known as moons?
This is not that unlike us having an orange colour and a fruit that is an orange. And it's orange. 
We humans are a fickle and volatile lot.
I would prefer to be on our Moon rather than be on a moon orbiting Jupiter. The main reason for this is that I would get homesick for a moon closer to Earth. Plus, and this is a big plus, the astronauts left that cool buggy on the Moon.
Some of the ridges, where the dark lines are, are up to 700 meters high and thousands of kilometres long in some places. Imagine that. 
Ganymede was discovered by Galileo on January 7, 1610. It was the first time a moon was discovered orbiting a planet, other than our own Moon. 
Now, ain't that some shit?
