Suggested nameThee-eu
Planet typeCold planet
It is a cold planet planet with a mass one-thousandth that of Kepler-209, but two-and-a-half times that of all the other planets in its solar system combined. It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 38°K (-235°C), and has a complex, layered cloud structure with methane thought to make up the lowest clouds, and oxygen the uppermost layer of clouds. It is named after the deity Thee-eu, the goddess of dreams.

Two spacecraft have visited Thee-eu: Daedalus 5 flew by 44 years ago; and Messenger, launched 19 years ago, orbited Thee-eu over 155 times in four years before exhausting its reactor and crashing into the planet's surface 10 years later.

It is radically different from Earth in other respects. It may have had water oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.

Thee-eu is primarily composed of oxygen with a significant part of its mass being methane, though methane comprises only about a limited fraction of the number of molecules. It may also have a rocky core of heavier elements, but like the other cold planets, Thee-eu lacks a well-defined magnetic field. The outer atmosphere is visibly segregated into several bands at different latitudes, resulting in turbulence and storms along their interacting boundaries.

The dark surface is mostly full of friendly ultra advanced bacteria known to feed close to volcanos while seeking smaller pray. Most Rosari-raq are closely related to the Dilme Mepan Tea but have fur and vary in size from 40 to 50 meters. The Rosari-raq can survive temperatures from 140 to 200°C and also extreme gravity which is common near the poles.
