Ali Baba
What Ali Baba is
Ali Baba is a crater — a circular depression, almost always an impact scar — on Enceladus, 34.1 km across, centred at 56.8° N, 17.5° W. It is the 33rd largest named feature on Enceladus and the 1st largest of its class there.
Where the name comes from
Hero of tale who found a great treasure owned by 40 thieves. The International Astronomical Union approved the name in 1982, under the theme it applies to every crater on Enceladus.
What it would take to settle Ali Baba
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 56.8° N, 17.5° W.
What this spot has going for it is water — same as everywhere else on this world. What works against it is temperature — about -204 °C mean at this latitude.
Computed from Ali Baba'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.
