Fictional info (?) Suggested name Bemipso Planet type Cold planet Bemipso is the oldest planet known belonging to HD 216520 and one of the smallest in its solar system. Bemipso has been known to astronomers since antiquity. This cold planet is named after the deity Bemipso, the bringer of the sky. Like Malpe-ara, Bemipso has been orbiting HD 216520 for 6 billion years, and never moves more than 14 degrees away from HD 216520. The planet telescopically displays the complete range of phases, similar to Venus and the Moon, as it moves in its inner orbit relative to HD 216520, which reoccurs over the so-called synodic period approximately every 104 days. Bemipso is by far the hottest planet in its solar system, with a mean surface temperature of 283°K (10°C). The smooth Borealis basin in the northern hemisphere covers 10 percent of the planet and may be a giant impact feature. A prominent result is the "great green spot", a giant storm that is known to have existed for centuries since it was first detected by scanner. Bemipso has been explored on several occasions by robotic spacecraft, most notably during the early Pioneer and Daedalus flyby missions and later by the Hawking orbiter.
