The biggest problem with settling on Jupiter is finding a place to land. There is no actual surface to the planet, per se. Jupiter’s body goes from molecular hydrogen to metallic hydrogen (that’s hydrogen under so much pressure that it has become a liquid metal), and finally a solid core under so much pressure nothing could ever realistically reach it. If you crack the case on landing, you’re still going to want to look out for asteroids. Because Jupiter is so massive (more than twice as large as all the other planets combined), it has an enormous gravitational pull which tends to grab every passing speck of stuff passing anywhere near it. In fact, we’re starting to suspect that Jupiter has actually saved Earth from a number of planet-killers over the eons.
