Verda
From Kerbal Space Program Wiki
Verda is an object in the Tuun System. It is described in the files as "A quiet moon", however, elsewhere in the files it is listed as orbiting Tuun directly, which would make it a planet.
Verda has slightly more gravity than Kerbin, and has water oceans and an oxygenated atmosphere, which, along with the name, suggest this may be a habitable, potentially vegetated, world. It has a purple planetshine color.
