Which is bigger, Babylon 5, a Super Star Destroyer, or Starfleet Spacedock? Your answer can be found in this chart, which renders a few dozen sci-fi spaceships in equivalent scale. The above is a one-quarter version of the original. The real-deal breaks it down into 1 pixel = 10 meters, which still requires a 2000 x 2000 resolution GIF to cram it all in.
Of course, that’s the abridged version, with just a greatest hits collection from Star Trek, Star Wars, Babylon 5, and a few other notables. The granddaddy is available at Merzo.net, wherein Jeff Russell offers eight different resolutions of an encyclopedic collection of fictional space characters, vessels and stations. Scale down to Yoda and up to a Dyson Sphere. And before you Empire-lovers out there get all uppity with your Death Star size swagger, just remember, Ringworld punks you easier than Wedge Antilles ever did.
Hat tip to John Sheesley for the impetus.
