Hardin Fretum
What Hardin Fretum is
Hardin Fretum is a fretum — a strait — a narrow channel connecting two larger bodies of liquid — on Titan, 246 km across, centred at 57.3° N, 42.2° E. It is the 65th largest named feature on Titan and the 1st largest of its class there.
Where the name comes from
Salvor Hardin, fictional character in Isaac Asimov's Foundation Series, first Mayor of the planet Terminus. The International Astronomical Union approved the name in 2015, under the theme it applies to every fretum on Titan.
What it would take to settle Hardin Fretum
Titan scores 32.6 as a world. That number is the same for every square metre of it — but sunlight, water, radiation and the ground under your feet are not. This is the same question asked at 57.3° N, 42.2° E.
What this spot has going for it is known ground — 5,737 km from Huygens (2005). What works against it is temperature — about -180 °C mean at this latitude.
Computed from Hardin Fretum's catalogued latitude, longitude and feature class — 74% of the model's weight had a basis here, and 2 axes were dropped as not applicable to Titan (radiation geometry, earth link). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on Titan and are already counted in the world's own index, not again here.
What this cannot see: elevation. Slope, local shadowing and the polar “peaks of eternal light” — ridge tops near the poles of a barely tilted world that catch sun almost continuously while a crater floor kilometres away never does — need a terrain model this does not have. Where a real mission targets a pole, that is usually why.
