Europa · Large ringed feature · 72nd largest named feature

Tyre

Greek; the seashore from which Zeus abducted Europa. Changed from Tyre Macula.

What Tyre is

Tyre is a large ringed feature — a multi-ring impact basin, the largest class of impact structure there is — on Europa, 149 km across, centred at 33.6° N, 146.6° W. It is the 72nd largest named feature on Europa and the 1st largest of its class there.

Where the name comes from

Greek; the seashore from which Zeus abducted Europa. Changed from Tyre Macula. The International Astronomical Union approved the name in 1997, under the theme it applies to every large ringed feature on Europa. Of the 2 features of this class catalogued on Europa, the naming categories run Greek (1), Celtic (1).

What it would take to settle Tyre

Europa scores 60.9 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 33.6° N, 146.6° W.

What this spot has going for it is water same as everywhere else on this world. What works against it is temperature about -158 °C mean at this latitude.

Computed from Tyre'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 Europa (earth link, known ground). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on Europa 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.
