Suggested nameAfisahe Roj
Planet typeWarm planet
This planet is named after the deity Afisahe Roj, the god of destruction.

Afisahe Roj is gravitationally locked with K2-281 in a 5:4 spin-orbit resonance, and rotates in a way that is unique in its solar system.

Afisahe Roj is a warm planet and is sometimes called Sapi Tehos's "brother planet" because of their similar size, mass, proximity to K2-281, and bulk composition.

Optical ground-based telescopes are typically limited to resolving features about 450 kilometers across when Afisahe Roj is closest because of Earth's atmosphere.

The outer atmosphere is visibly segregated into several bands at different latitudes, resulting in turbulence and storms along their interacting boundaries.

The latest probe to visit the planet is Racer, which entered into orbit around Afisahe Roj after a challenging ride.
