Patamalrus' atmosphere is very similar to Venus in terms of pressure and temperature. Unlike Venus, however, Patamalrus' atmosphere has a significant quantity of oxygen, both free and bound in sulphur dioxides. The surface is largely composed of magnesia with deposits of carbon. It is possible, if unlikely, that simple life may be developing on Patamalrus.
Computer modeling suggests that the powerful solar winds from the Tereshkova stars will blow off Patamalrus' atmosphere in a few million years, lowering the temperature on the surface to the −70s.
