Mercury · Crater · 263rd largest named feature

Prokofiev

Sergey; Russian composer (1891-1953).

What Prokofiev is

Prokofiev is a crater — a circular depression, almost always an impact scar — on Mercury, 112 km across, centred at 85.8° N, 62.9° E in the Borealis quadrangle. It is the 263rd largest named feature on Mercury and the 169th largest of its class there.

Where the name comes from

Sergey; Russian composer (1891-1953). The International Astronomical Union approved the name in 2012, under the theme it applies to every crater on Mercury. Of the 449 features of this class catalogued on Mercury, the naming categories run France (36), United States (35), Japan (33), Italy (31).

What it would take to settle Prokofiev

Mercury scores 46 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 85.8° N, 62.9° E.

What this spot has going for it is water inside the polar zone where Mercury keeps its ice. What works against it is sunlight 7% of the sunlight the sunniest latitude on Mercury gets.

Computed from Prokofiev's catalogued latitude, longitude and feature class — 68% of the model's weight had a basis here, and 3 axes were dropped as not applicable to Mercury (radiation geometry, earth link, known ground). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on Mercury 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.
