Ganymede · Crater · 104th largest named feature

Kadi

Babylonian goddess of justice.

What Kadi is

Kadi is a crater — a circular depression, almost always an impact scar — on Ganymede, 87 km across, centred at 47.7° N, 178.5° W. It is the 104th largest named feature on Ganymede and the 44th largest of its class there.

Where the name comes from

Babylonian goddess of justice. The International Astronomical Union approved the name in 1985, 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 Kadi

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 47.7° N, 178.5° W.

What this spot has going for it is water same as everywhere else on this world. What works against it is radiation geometry inside the open-field polar cap, where the plasma gets down.

Computed from Kadi'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.
