Yunan
What Yunan is
Yunan is a crater — a circular depression, almost always an impact scar — on Enceladus, 19.5 km across, centred at 54.0° N, 74.2° E. It is the 45th largest named feature on Enceladus and the 13th largest of its class there.
Where the name comes from
Fictional king of Persian city in the tale "The Tale of the Vizier and the Sage Duban." The International Astronomical Union approved the name in 2009, under the theme it applies to every crater on Enceladus.
What it would take to settle Yunan
Enceladus scores 54.8 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 54.0° N, 74.2° E.
What this spot has going for it is water — same as everywhere else on this world. What works against it is temperature — about -203 °C mean at this latitude.
Computed from Yunan's catalogued latitude, longitude and feature class — 68% of the model's weight had a basis here, and 3 axes were dropped as not applicable to Enceladus (radiation geometry, earth link, known ground). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on Enceladus 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.
