Suggested name | Shura Hyobu-byo |
Planet type | Cold planet |
It has the longest rotation period (445 days) of any planet in its solar system and rotates in the opposite direction to most other planets.
It is named after the deity Shura Hyobu-byo, the messenger of dreams.
The planet telescopically displays the complete range of phases, similar to Venus and the Moon, as it moves in its inner orbit relative to Kepler-1201, which reoccurs over the so-called synodic period approximately every 110 days.
Shura Hyobu-byo is a cold planet and is sometimes called Earth's "sister planet" because of their similar size, mass, proximity to Kepler-1201, and bulk composition. The molecular hydrogen has probably photodissociated, and the free water vapor has been swept into interplanetary space by the solar wind because of the lack of a 2H2O layer.
The rotational period and seasonal cycles of Shura Hyobu-byo are likewise similar to those of Earth, as is the tilt that produces the seasons.
Its apparent magnitude reaches -3, which is surpassed only by Yannyako Hyu, Kuze'chijo, and Kepler-1201.
Its north and south poles, therefore, lie where most other planets have their equators. |
