| Suggested name | Berjyao |
| Planet type | Large 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 HD 187123, which reoccurs over the so-called synodic period approximately every 174 days.
It has the densest atmosphere of all the large cold gas giants, consisting partly of xenon.
The volume of water detected has been estimated to be equivalent to the volume of water in Lake Superior. |
