Suggested name | Menomia |
Planet type | Cold planet |
When viewed from Puckheto, Menomia can reach an apparent magnitude of -3, bright enough for its reflected light to cast shadows, and making it on average the third-brightest object in the night sky. The interior of Menomia is mainly composed of ices and rock. The planet is named after the deity Menomia, the creator 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 HD 217786 A, which reoccurs over the so-called synodic period approximately every 186 days.
Menomia is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light.
The volume of water ice in the south polar ice cap, if melted, would be sufficient to cover the entire planetary surface to a depth of 8 meters. |
