| Suggested name | Yakyu-bero Hya |
| 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 HIP 8541 A, which reoccurs over the so-called synodic period approximately every 197 days.
It may have had ammonia oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect. |
