Fictional info (?) Suggested name Trinnaq Steph Planet type Cold planet It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 35°K (-238°C), and has a complex, layered cloud structure with ethane thought to make up the lowest clouds, and nitrogen the uppermost layer of clouds. It is named after the deity Trinnaq Steph, the goddess of good fortune. It may have had hydrogen oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect. The hydrogen has probably photodissociated, and the free nitrogen has been swept into interplanetary space by the solar wind because of the lack of a planetary magnetic field. There are ongoing investigations assessing the future terraforming potential of Trinnaq Steph, as well as the possibility of extant life.
