Promontorium Kelvin

William Thomson, Lord Kelvin; Scottish natural philosopher (1824-1907).

What Promontorium Kelvin is

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.

Where the name comes from

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).

What it would take to settle Promontorium Kelvin

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.
