Fictional info (?) Suggested name Chikomyo Planet type Small hot gas planet It is the second-brightest natural object in the night sky after Yagokudo Jo, reaching an apparent magnitude of -5 - bright enough to cast shadows at night and, often, visible to the naked eye in broad daylight. The planet is named after the deity Chikomyo, the messenger of the sea. 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 135°K (-138°C) at night to 735°K (462°C) during the day across the equatorial regions. It has the densest atmosphere of the known small hot gas planets, consisting of huge amounts of krypton. The atmospheric pressure at the planet's surface is 0.001 bar, or roughly the pressure found 1170 m under the oceans of Yagokudo Jo. The outer atmosphere is visibly segregated into several bands at different latitudes, resulting in turbulence and storms along their interacting boundaries.
