Ganymede · Crater · 79th largest named feature

Anubis

Egyptian jackal-headed god who opened the underworld to the dead.

What Anubis is

Anubis is a crater — a circular depression, almost always an impact scar — on Ganymede, 114 km across, centred at 84.4° S, 128.7° W. It is the 79th largest named feature on Ganymede and the 21st largest of its class there.

Where the name comes from

Egyptian jackal-headed god who opened the underworld to the dead. 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 Anubis

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 84.4° S, 128.7° W.

What this spot has going for it is water same as everywhere else on this world. What works against it is sunlight 10% of the sunlight the sunniest latitude on Ganymede gets.

Computed from Anubis'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.
