Arev Dorsa
What Arev Dorsa is
Arev Dorsa is a dorsum — a ridge — on Venus, 420 km across, centred at 52.0° S, 144.0° W in the Barrymore quadrangle. It is the 461st largest named feature on Venus and the 92nd largest of its class there.
Where the name comes from
Armenian female solar deity. The International Astronomical Union approved the name in 2000, under the theme it applies to every dorsum on Venus. Of the 99 features of this class catalogued on Venus, the naming categories run Slavic (9), Siberia (8), Greek (6), Lithuania (5).
What it would take to settle Arev Dorsa
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 52.0° S, 144.0° W.
What this spot has going for it is known ground — 5,783 km from Vega 2 (1985). What works against it is water — same as everywhere else on this world.
Computed from Arev Dorsa'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.
