Perpennia
What Perpennia is
Perpennia is a crater — a circular depression, almost always an impact scar — on Vesta, 21.4 km across, centred at 23.0° S, 101.2° W. It is the 54th largest named feature on Vesta and the 38th largest of its class there.
Where the name comes from
Roman vestal virgin (c. 100-70 B.C.). 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 Perpennia
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 23.0° S, 101.2° W.
What this spot has going for it is sunlight — 93% of the sunlight the sunniest latitude on Vesta gets. What works against it is water — same as everywhere else on this world.
Computed from Perpennia'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.
