Suggested nameYtijohu Puse
Planet typeCold planet
Ytijohu Puse is the oldest planet known belonging to K2-123 and one of the largest in its solar system. Ytijohu Puse is similar in composition to Edyf Ib, and both have different bulk chemical composition from that of the larger cold planets. It is named after the deity Ytijohu Puse, the demon of good fortune.

The sulfur dioxide 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.

Ytijohu Puse's dense clouds make observation of its surface difficult in ultraviolet light, and the first detailed maps did not emerge until the arrival of the Magellan orbiter 58 years ago.

Its apparent magnitude reaches -3, which is surpassed only by Edyf Ib, Zeru, and K2-123. Optical ground-based telescopes are typically limited to resolving features about 435 kilometers across when Ytijohu Puse is closest because of Edyf Ib's atmosphere.
