The Moon · Crater · 720th largest named feature

Wilson

Alexander; Scottish astronomer (1714-1786); Charles Thomson Rees; Scottish physicist (1869-1959); Ralph Elmer; American astronomer (1886-1960).

What Wilson is

Wilson is a crater — a circular depression, almost always an impact scar — on The Moon, 66.6 km across, centred at 69.3° S, 42.8° W in the Bailly quadrangle. It is the 720th largest named feature on The Moon and the 507th largest of its class there.

Where the name comes from

Alexander; Scottish astronomer (1714-1786); Charles Thomson Rees; Scottish physicist (1869-1959); Ralph Elmer; American astronomer (1886-1960). The International Astronomical Union approved the name in 1935, under the theme it applies to every crater on The Moon. Of the 1615 features of this class catalogued on The Moon, the naming categories run Germany (234), American (229), France (163), Great Britain (160).

What it would take to settle Wilson

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 69.3° S, 42.8° W.

What this spot has going for it is earth link near side — Earth stands 15° above the horizon and never moves. What works against it is water outside the ice-bearing latitudes.

Computed from Wilson'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.

Wilson's satellite craters

The IAU names smaller craters around a major one by letter. Wilson has 4, and each shares the parent's namesake rather than carrying one of its own.
