surface_area_largeToday features a short but vivid post borrowed from the futurist/science fiction/space blog io9 (which in turn took it from XKCD). Above is a map of all the surfaces of the solar system’s planets and moons flattened out and stitched together. The map was created by Randall Munroe and it does a superb job of explaining the relative size of rocky objects in the solar system. For obvious reasons the gas giants (and the sun!) have been excluded, but so too have small rocks and dust. For fun (um, I hope), the mapmaker also included an area equivalent to all human skin–which, distressingly, seems to be about the size of Hainan.

This map also emphasizes my most ardent fantasy of solar system colonization: I don’t really want to set up shop on Umbiel or Ceres, but I have a long-lasting interest in colonizing Venus. Sadly most of the rest of humankind is having trouble grasping this concept (possibly because the surface of Venus is a molten hellscape featuring boiling lead, sulfuric acid rain, and crushing pressure).  Remember though, we don’t need to ever go down to the Venutian surface: we can hang around in floating bouncy castles drifting through the balmy spring at the top of the atmosphere. Imagine taking your family zeppelin out for a night on the floating town! All of the people who express such an unwholesome interest in cold resource-poor Mars should pause to reexamine its relative area on Mr. Munroe’s excellent map!
