Seker
What Seker is
Seker is a crater — a circular depression, almost always an impact scar — on Ganymede, 103 km across, centred at 39.2° S, 14.6° E. It is the 85th largest named feature on Ganymede and the 26th largest of its class there.
Where the name comes from
Egyptian god of the dead at Memphis. The International Astronomical Union approved the name in 1988, under the theme it applies to every crater on Ganymede. Of the 129 features of this class catalogued on Ganymede, the naming categories run Egypt (42), Assyro-Babylonian (30), Phoenician (18), Sumerian (16).
What it would take to settle Seker
Ganymede scores 55 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 39.2° S, 14.6° E.
What this spot has going for it is water — same as everywhere else on this world. What works against it is temperature — about -163 °C mean at this latitude.
Computed from Seker's catalogued latitude, longitude and feature class — 84% of the model's weight had a basis here, and 2 axes were dropped as not applicable to Ganymede (earth link, known ground). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on Ganymede 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.
