Caloris Montes
What Caloris Montes is
Caloris Montes is a mons — a mountain — on Mercury, 1,023 km across, centred at 31.5° N, 174.2° W in the Shakespeare quadrangle. It is the 7th largest named feature on Mercury and the 1st largest of its class there.
Where the name comes from
"Hot mountains"; surface temperature hottest near this position. The International Astronomical Union approved the name in 1976.
What it would take to settle Caloris Montes
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 31.5° N, 174.2° W.
What this spot has going for it is sunlight — 85% of the sunlight the sunniest latitude on Mercury gets. What works against it is water — outside the ice-bearing latitudes.
Computed from Caloris Montes'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.
