Lucilla
What Lucilla is
Lucilla is a crater — a circular depression, almost always an impact scar — on Vesta, 19.3 km across, centred at 76.0° S, 60.9° W. It is the 60th largest named feature on Vesta and the 44th largest of its class there.
Where the name comes from
Annia; Roman Empress, mother of M. Aurelius, married to Emperors L. Verus, and then to Ti. Claudius (c. 150-182). The International Astronomical Union approved the name in 2014, under the theme it applies to every crater on Vesta.
What it would take to settle Lucilla
Vesta scores 56.2 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 76.0° S, 60.9° W.
What this spot has going for it is temperature — about -105 °C mean at this latitude. What works against it is water — same as everywhere else on this world.
Computed from Lucilla'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 Vesta (radiation geometry, earth link, known ground). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on Vesta 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.
