Le Gentil

Guillaume Hyazinthe; French astronomer (1725-1792).

What Le Gentil is

Le Gentil is a crater — a circular depression, almost always an impact scar — on The Moon, 125 km across, centred at 74.3° S, 76.0° W in the Bailly quadrangle. It is the 246th largest named feature on The Moon and the 111th largest of its class there.

Where the name comes from

Guillaume Hyazinthe; French astronomer (1725-1792). 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 Le Gentil

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 74.3° S, 76.0° W.

What this spot has going for it is known ground 341 km from LCROSS Probe (2009). What works against it is sunlight 27% of the sunlight the sunniest latitude on The Moon gets.

Computed from Le Gentil'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.

Le Gentil's satellite craters

The IAU names smaller craters around a major one by letter. Le Gentil has 5, and each shares the parent's namesake rather than carrying one of its own.
