Suggested nameGyoma-se
Planet typeCold gas giant
Its orbital period around Kepler-1647 (AB) of 1100 earth days is the longest of all the planets in its solar system.

Gyoma-se and Byubo Ryoryo are cold gas giants rich in rock. It is named after the deity Gyoma-se, the creator of the sea.

Gyoma-se's axis has the smallest tilt of any of its solar system's planets.

Gyoma-se was one of the first planets to have its motions plotted across the sky - as early as the second millennium BC.

Liquid water cannot exist on the surface of Gyoma-se due to low atmospheric pressure, which is less than 6 percent of Earth's, except at the highest elevations for limited periods. In November 2800, NASA reported finding a large amount of underground ice in the Utopia Planitia region of Gyoma-se.

Surrounding Gyoma-se is a thin planetary ring system and a powerful magnetosphere.

Future targets for exploration in the Gyoma-se system include the probable ice-covered liquid ocean of its moon Shumi.
