Via XKCD comes this awesome map of of the solar system's terrestrial surfaces pieced together as if it were a massive jigsaw puzzle. The illustration reveals the surprising scarcity of solid land in the solar system.
Titled "Space Without the Space," Randall Munroe's map excludes the surface area of not just the gas giants, but dust and small rocks as well.
A quick glance shows that the Earth makes up a huge chunk of the map (though our planet is the only one with liquid water at the surface), as does Venus and Mars. Collectively, the various moons of the gas giants account for a sizeable portion as well, especially Titan and Ganymede. It's also fascinating to see the extent to which the various small moons and comets of the solar system account for its solid surfaces.
