Ashtart Tholus
What Ashtart Tholus is
Ashtart Tholus is a tholus — a small domical mountain or hill — on Venus, 138 km across, centred at 48.7° N, 113.0° W in the Kawelu Planitia quadrangle. It is the 900th largest named feature on Venus and the 11th largest of its class there.
Where the name comes from
Phoenician goddess of love, fertility and war; personification of planet Venus. The International Astronomical Union approved the name in 1985, under the theme it applies to every tholus on Venus. Of the 62 features of this class catalogued on Venus, the naming categories run Greek (5), Slavic (4), New Zealand (3), Japan (3).
What it would take to settle Ashtart Tholus
Venus scores 43 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 48.7° N, 113.0° W.
What this spot has going for it is known ground — 3,999 km from Venera 9 (1975). What works against it is water — same as everywhere else on this world.
Computed from Ashtart Tholus's catalogued latitude, longitude and feature class — 74% of the model's weight had a basis here, and 2 axes were dropped as not applicable to Venus (radiation geometry, earth link). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on Venus 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.
