The Moon · Crater · 1836th largest named feature

Bay

Zoltán Lajos; Hungarian physicist (1900-1992).

What Bay is

Bay is a crater — a circular depression, almost always an impact scar — on The Moon, 3.5 km across, centred at 88.8° S, 36.9° W in the Amundsen quadrangle. It is the 1836th largest named feature on The Moon and the 1509th largest of its class there.

Where the name comes from

Zoltán Lajos; Hungarian physicist (1900-1992). The International Astronomical Union approved the name in 2025, 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 Bay

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 88.8° S, 36.9° W.

What this spot has going for it is water inside the polar zone where The Moon keeps its ice. What works against it is sunlight 3% of the sunlight the sunniest latitude on The Moon gets.

Computed from Bay'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.
