At 1.35 m/s² gravity in an atmosphere denser than Earth's, a human with strapped-on wings could take off and fly. It is the only place in the Solar System where that is true.
Every figure below is tagged with where it came from. Measured means an instrument read it on or at the body; modeled means it was computed and never directly observed.
No world off Earth is habitable — the honest habitable fraction of every surface here is zero. What can be answered is how far each one sits from Earth along the seven axes a habitat has to buy its way out of. Titan scores 32.6 out of 100, on 100% coverage of the axes. The single worst axis here is access (13.0 km/s from LEO, 6.6 years one way); the one that most sets Titan apart from the other thirteen is available energy.
Delta-v sets what a launch costs; cruise time sets how much consumable, shielding and crew patience each kilogram of payload drags with it.
Both directions cost power continuously. A cold world burns reactor output to stay warm; a hot one has no cold sink to dump heat into at all.
Past the asteroid belt solar panels stop being an option and a settlement needs fission, which means importing fuel.
Nobody has ever measured long-term human health at any gravity between 0 and 1 g. Below about 0.1 g, anchoring anything — including yourself — becomes the design driver.
Huygens touched down on 14 January 2005 — the most distant landing ever made, and still the only one in the outer Solar System.
Unprotected survival: Minutes. You would need oxygen and heavy insulation, but no pressure suit — the pressure is survivable.
The bedrock is water ice, hard as granite at 94 K, over a subsurface ammonia-water ocean. The liquid on the surface is methane and ethane.
The IAU has approved 304 names on Titan, each drawn from a theme the naming committee chose for this world. Every name in the scene above is one of them, placed at its catalogued coordinates.
Imagery is public-domain NASA/USGS mission data, streamed live from NASA Trek as a plate-carrée tile pyramid and draped on our own sphere — no third-party globe library and no cached copy of anyone else's map.
