Venus · Crater · 1523rd largest named feature

Lenore

Greek first name (form of Helen).

What Lenore is

Lenore is a crater — a circular depression, almost always an impact scar — on Venus, 15.5 km across, centred at 38.7° N, 67.8° W in the Beta Regio quadrangle. It is the 1523rd largest named feature on Venus and the 440th largest of its class there.

Where the name comes from

Greek first name (form of Helen). The International Astronomical Union approved the name in 1994, under the theme it applies to every crater on Venus. Of the 881 features of this class catalogued on Venus, the naming categories run American (88), Russia (55), France (47), England (47).

What it would take to settle Lenore

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 38.7° N, 67.8° W.

What this spot has going for it is known ground 814 km from Venera 9 (1975). What works against it is water same as everywhere else on this world.

Computed from Lenore'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.
