Tsui Goab Tholus
What Tsui Goab Tholus is
Tsui Goab Tholus is a tholus — a small domical mountain or hill — on Io, 48.5 km across, centred at 0.2° S, 163.0° W. It is the 204th largest named feature on Io and the 3rd largest of its class there.
Where the name comes from
Hottentot (southern Africa) supreme being, associated with thunder. The International Astronomical Union approved the name in 2003, under the theme it applies to every tholus on Io. Of the 3 features of this class catalogued on Io, the naming categories run Greek (2), Hottentot (1).
What it would take to settle Tsui Goab Tholus
Io scores 76.7 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 0.2° S, 163.0° W.
What this spot has going for it is sunlight — 100% of the sunlight the sunniest latitude on Io gets. What works against it is water — same as everywhere else on this world.
Computed from Tsui Goab Tholus's catalogued latitude, longitude and feature class — 84% of the model's weight had a basis here, and 2 axes were dropped as not applicable to Io (earth link, known ground). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on Io 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.
