Hervor Corona

Norse fertility goddess.

What Hervor Corona is

Hervor Corona is a corona — an oval feature raised by rising material beneath the crust — on Venus, 250 km across, centred at 25.5° S, 91.0° W in the Helen Planitia quadrangle. It is the 669th largest named feature on Venus and the 158th largest of its class there.

Where the name comes from

Norse fertility goddess. The International Astronomical Union approved the name in 1991, under the theme it applies to every corona on Venus. Of the 340 features of this class catalogued on Venus, the naming categories run India (16), Greek (14), Celtic (12), Roman (11).

What it would take to settle Hervor Corona

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 25.5° S, 91.0° W.

What this spot has going for it is sunlight 90% of the sunlight the sunniest latitude on Venus gets. What works against it is water same as everywhere else on this world.

Computed from Hervor Corona'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.
