Promontorium Kelvin is a promontorium — a cape, where a highland juts into a plain — on The Moon, 45 km across, centred at 26.9° S, 33.4° W in the Mare Humorum quadrangle. It is the 1082nd largest named feature on The Moon and the 5th largest of its class there.
William Thomson, Lord Kelvin; Scottish natural philosopher (1824-1907). The International Astronomical Union approved the name in 1935, under the theme it applies to every promontorium on The Moon. Of the 9 features of this class catalogued on The Moon, the naming categories run France (3), Greek (2), Russia (2), Scotland (1).
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 26.9° S, 33.4° W.
What this spot has going for it is earth link — near side — Earth stands 48° above the horizon and never moves. What works against it is water — outside the ice-bearing latitudes.
Computed from Promontorium Kelvin'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.
