| Suggested name | Atthys-tay |
| Planet type | Huge cold gas giant |
| The planet telescopically displays the complete range of phases, similar to Venus and the Moon, as it moves in its inner orbit relative to @STARNAME, which reoccurs over the so-called synodic period approximately every 151 days.
It has the densest atmosphere of the known huge cold gas giants, consisting mostly of formaldehyde. . The ammonia has probably photodissociated, and the free formaldehyde has been swept into interplanetary space by the solar wind because of the lack of a planetary magnetic field.
It was the one of the first exoplanets visited by a spacecraft, and one of the first to be successfully landed on.
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 13 meters. |
