Fictional info (?)
Suggested nameTopi Hya
Planet typeLarge hot gas giant
This planet is named after the deity Topi Hya, the messenger of good fortune.

Topi Hya is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light. It may have had ethane oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.

As the closest planet to Ruida Nekishu, Topi Hya has been a prime target for early extra solar exploration.
