The Moon · Crater · 1034th largest named feature

Shirakatsi

Anania; Armenian geographer (620(?)-685(?)).

What Shirakatsi is

Shirakatsi is a crater — a circular depression, almost always an impact scar — on The Moon, 48.1 km across, centred at 12.2° S, 128.6° E in the Langemak quadrangle. It is the 1034th largest named feature on The Moon and the 795th largest of its class there.

Where the name comes from

Anania; Armenian geographer (620(?)-685(?)). The International Astronomical Union approved the name in 1979, 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 Shirakatsi

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 12.2° S, 128.6° E.

What this spot has going for it is sunlight 98% of the sunlight the sunniest latitude on The Moon gets. What works against it is water outside the ice-bearing latitudes.

Computed from Shirakatsi'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.
