| Planet type | Hot planet |
| Guhyuju Cho is the largest and most round planet in its solar system. It has the longest rotation period (445 days) of any planet in its solar system and rotates in the opposite direction to most other planets.
It is named after the deity Guhyuju Cho, the messenger of the sky.
Guhyuju Cho is a hot planet and is sometimes called Earth's "sister planet" because of their similar size, mass, proximity to K2-198, and bulk composition. Guhyuju Cho's surface is a barren desertscape interspersed with slab-like rocks and is periodically resurfaced by volcanism.
Guhyuju Cho is the site of Robusto Montanus, the tallest volcano and second-highest known mountain in its solar system, and of Valles Marineris, one of the largest canyons in its solar system. |
