Jupiter is so huge that the Earth could sink into it easily. This gas planet is second in size to the Sun only, and its powerful gravity protects our planet from the comets and asteroids.
What do we know about Titan, a moon of Saturn? It’s Earth-like in some ways, there are lakes, rivers, clouds, and rains, but it’s really cold there. However, the thick atmosphere protects the surface from radiation, and perhaps the first extraterrestrial colony of humanity will appear on Titan instead of Mars.
