| Suggested name | Yuhyu |
| Planet type | Hot planet |
| This hot planet is named after the deity Yuhyu, the spirit of the sea.
The planet telescopically displays the complete range of phases, similar to Venus and the Moon, as it moves in its inner orbit relative to HD 168746, which reoccurs over the so-called synodic period approximately every 64 days.
The ozone has probably photodissociated, and the free ammonia has been swept into interplanetary space by the solar wind because of the lack of a planetary magnetic field.
Yuhyu was one of the first planets to have its motions plotted across the sky - as early as the second millennium BC.
As the closest planet to Zeeherya Ru, Yuhyu has been a prime target for early interplanetary exploration. |
