Ypoa Lacus

Lake in Paraguay.

What Ypoa Lacus is

Ypoa Lacus is a lacus — a small dark plain — on Titan, 39.2 km across, centred at 73.4° N, 132.2° W. It is the 217th largest named feature on Titan and the 40th largest of its class there.

Where the name comes from

Lake in Paraguay. The International Astronomical Union approved the name in 2017, under the theme it applies to every lacus on Titan. Of the 93 features of this class catalogued on Titan, the naming categories run United States (4), Canada (3), Japan (3), China (2).

What it would take to settle Ypoa Lacus

Titan scores 32.6 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 73.4° N, 132.2° W.

What this spot has going for it is water inside the polar zone where Titan keeps its ice. What works against it is temperature about -180 °C mean at this latitude.

Computed from Ypoa Lacus's catalogued latitude, longitude and feature class — 74% of the model's weight had a basis here, and 2 axes were dropped as not applicable to Titan (radiation geometry, earth link). Gravity, pressure, delta-v and distance from the Sun are the same everywhere on Titan 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.
