Fictional info (?) Suggested name Rebiryo Planet type Warm planet It is the second-brightest natural object in the night sky after Pechi Basa, reaching an apparent magnitude of -5 - bright enough to cast shadows at night and, rarely, visible to the naked eye in broad daylight. Rebiryo is the oldest planet known belonging to K2-249 and one of the smallest in its solar system. It is named after the deity Rebiryo, the creator of the underworld. Plans have been proposed for rovers or more complex missions, but they are hindered by Rebiryo's hostile surface conditions. The rotational period and seasonal cycles of Rebiryo are likewise similar to those of Earth, as is the tilt that produces the seasons. Future astrobiology missions are planned, including the Rebiryo 1200 and ExoRebiryo rovers. It may also have a rocky core of heavier elements, but like the other warm planets, Rebiryo lacks a well-defined solid surface.
