Dorsa Sorby
What Dorsa Sorby is
Dorsa Sorby is a dorsum — a ridge — on The Moon, 76 km across, centred at 18.6° N, 13.7° E in the Mare Serenitatis quadrangle. It is the 593rd largest named feature on The Moon and the 31st largest of its class there.
Where the name comes from
Henry Clifton; British Earth scientist (1826-1908). The International Astronomical Union approved the name in 1976, under the theme it applies to every dorsum on The Moon. Of the 39 features of this class catalogued on The Moon, the naming categories run Great Britain (8), American (6), Germany (5), Switzerland (4).
What it would take to settle Dorsa Sorby
The Moon scores 29.1 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 18.6° N, 13.7° E.
What this spot has going for it is earth link — near side — Earth stands 67° above the horizon and never moves. What works against it is water — outside the ice-bearing latitudes.
Computed from Dorsa Sorby's catalogued latitude, longitude and feature class — 84% of the model's weight had a basis here, and one axis was dropped as not applicable to The Moon (radiation geometry). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on The Moon 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.
