Fictional info (?)
Suggested nameJuba-nyunyu
Planet typeTerrestrial
Orbiting within Myubi-myo's orbit, Juba-nyunyu is an inferior planet and never appears to venture far from Kepler-1668; its maximum angular distance from Kepler-1668 (elongation) is 24 degrees.

It is named after the deity Juba-nyunyu, the spirit of chaos.

Having almost no atmosphere to retain heat, it has surface temperatures that vary diurnally more than on any other planet in its solar system, ranging from 115°K (-158°C) at night to 980°K (707°C) during the day across the equatorial regions.

The oxygen has probably photodissociated, and the free methane 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 past habitability potential of Juba-nyunyu, as well as the possibility of extant life.

Juba-nyunyu can easily be seen from Myubi-myo with the naked eye, as can its yellowish coloring.

The largest moon is populated by strange stone-age oceanic creatures called the "Gyahyo". They feed scattered in groups by seeking smaller pray if it is available. Most Gyahyo are related to the Pyarabya but have fur and vary in size from 50 to 80 cm. The Gyahyo can thrive at temperatures from 50 to 140°C but are killed by intense weather which is common on Juba-nyunyu.
