People of Earth talk about Earth too much. So in this thread post about your favourite thing in the entire universe that is not Earth.

My favourite thing, at least in the Solar System, is Titan, the largest moon of Saturn, and the second largest moon in the Solar System. It is 50% larger and 80% more massive than the (Earth's) Moon. It has lakes of methane. One of my favourte images is this one, of a radar scan of its north polar region:



You can almost see yourself setting sail in its oceans of smelly liquid. It's methane cycle is very much akin to the water cycle of Earth. It is a planet-like moon.

Europa is badass too, but I think Titan is the best.
