Fictional info (?) Suggested name Cefran'porie Planet type Cold planet It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 33°K (-240°C), and has a complex, layered cloud structure with hydrogen peroxide thought to make up the lowest clouds, and 2H2O the uppermost layer of clouds. This planet is named after the deity Cefran'porie, the demon of chaos. As seen from Kepler-1189, in a frame of reference that rotates with the orbital motion, it appears to rotate only once every two years. Its orbital eccentricity is the largest of all known planets in its solar system; at perihelion, Cefran'porie's distance from Kepler-1189 is only about two-thirds (or 53 pct) of its distance at aphelion. Two spacecraft have visited Cefran'porie: Daedalus 4 flew by 27 years ago; and Messenger, launched 26 years ago, orbited Cefran'porie over 70 times in four years before exhausting its plasma drive and crashing into the planet's surface 5 years later. It is radically different from Earth in other respects. The rotational period and seasonal cycles of Cefran'porie are likewise similar to those of Earth, as is the tilt that produces the seasons. Cefran'porie is the site of Ars Peak, the tallest volcano and second-highest known mountain in its solar system, and of Valles Marineris, one of the largest canyons in its solar system. There are ongoing investigations assessing the past habitability potential of Cefran'porie, as well as the possibility of extant life. The volume of water ice in the south polar ice cap, if melted, would be sufficient to cover the entire planetary surface to a depth of 10 meters.
