Fictional info (?)
Suggested nameSedys'ga
Planet typeHot planet
Sedys'ga is the largest and most crater filled planet in its solar system. It is the second-brightest natural object in the night sky after Dabos Mir, reaching an apparent magnitude of -5 - bright enough to cast shadows at night and, often, visible to the naked eye in broad daylight.

It is named after the deity Sedys'ga, the messenger of chaos.

Like Dabos Mir, Sedys'ga has been orbiting K2-104 for 0.8 billion years, and never exceeds 25 degrees away from K2-104.
