Jacheongbi
What Jacheongbi is
Jacheongbi is a crater — a circular depression, almost always an impact scar — on Ceres, 31 km across, centred at 69.2° S, 2.3° E. It is the 90th largest named feature on Ceres and the 70th largest of its class there.
Where the name comes from
Korean Earth goddess who brought 5 grains to Jeju island, and began agriculture. The International Astronomical Union approved the name in 2017, under the theme it applies to every crater on Ceres. Of the 115 features of this class catalogued on Ceres, the naming categories run Roman (6), Sumerian (5), Egypt (5), Polynesia (3).
What it would take to settle Jacheongbi
Ceres scores 43.8 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 69.2° S, 2.3° E.
What this spot has going for it is water — inside the polar zone where Ceres keeps its ice. What works against it is sunlight — 36% of the sunlight the sunniest latitude on Ceres gets.
Computed from Jacheongbi'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 Ceres (radiation geometry, earth link, known ground). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on Ceres 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.
