| Suggested name | Rihi |
| Planet type | Hot gas giant |
| The planet is named after the deity Rihi, the creator of the underworld.
Like Yokamya To, Rihi has been orbiting WASP-174 within Nyouwa's orbit as an inferior planet, and never moves more than 18 degrees away from WASP-174.
Rihi was one of the first planets to have its motions plotted across the sky - as early as the second millennium BC.
Future astrobiology missions are planned, including the Rihi 1600 and ExoRihi rovers.
Optical ground-based telescopes are typically limited to resolving features about 420 kilometers across when Rihi is closest because of Yokamya To's atmosphere. |
