With the lowest density of any major moon in the solar system, Tethys is likely composed almost entirely of water ice with very little rock. Its surface contains the usual craters, ridges, and cryovolcanoes you might expect from a body of its size and composition, with one notable impact crater being over 400 kilometers wide. To be honest, Tethys isn't a terribly exciting moon. It's a large, unusually pure snowball in space.
At least, that used to be true: after today, it will be your home.
Tethys was discovered on 21 March 1684 by G. D. Cassini.
This world is truly tiny. The goal for the water level is incredibly low. This will make it hard to reach Paradise habitability, because the range which is considered 'paradise' is really small: It’s only 6,000cm! Use a couple of Cloud Seeders to put it into habitable stats but do not let it upgrade them to Level X.
You do need to get rid of the frozen in ice part before warming up the world. It does not take much to flood this one.
Tethys is named after Tethys who was a Titan daughter of Uranus and Gaia, sister and wife of the Titan Oceanus, mother of the river gods and the Oceanids.
Tethys is composed of water ice, that's because of its low density.
