| Suggested name | Renar |
| Planet type | Cold planet |
| Orbiting within Zuroz's orbit, Renar is an inferior planet and never appears to venture far from K2-194; its maximum angular distance from K2-194 (elongation) is 77 degrees.
When viewed from Zuroz, Renar can reach an apparent magnitude of -3, bright enough for its reflected light to cast shadows, and making it on average the third-brightest object in the night sky. It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 28°K (-245°C), and has a complex, layered cloud structure with argon thought to make up the lowest clouds, and neon the uppermost layer of clouds. This cold planet is named after the deity Renar, the messenger of dreams.
The planet telescopically displays the complete range of phases, similar to Venus and the Moon, as it moves in its inner orbit relative to K2-194, which reoccurs over the so-called synodic period approximately every 110 days.
Renar's surface appears quite rippled and is similar in appearance to the Moon's, indicating that it has been geologically inactive for billions of years.
The ozone has probably photodissociated, and the free neon has been swept into interplanetary space by the solar wind because of the lack of a carbon dioxide layer. |
