Dennitsa Dorsa
What Dennitsa Dorsa is
Dennitsa Dorsa is a dorsum — a ridge — on Venus, 872 km across, centred at 85.6° N, 154.1° W in the Snegurochka Planitia quadrangle. It is the 221st largest named feature on Venus and the 46th largest of its class there.
Where the name comes from
Slavic goddess of day, light. The International Astronomical Union approved the name in 1985, 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 Dennitsa 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 85.6° N, 154.1° W.
What this spot has going for it is known ground — 6,207 km from Venera 9 (1975). What works against it is water — same as everywhere else on this world.
Computed from Dennitsa 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.
