Fictional info (?) Suggested name Bian'nome Planet type Cold planet Bian'nome is the strangest and most well-known planet in its solar system. This cold planet is named after the deity Bian'nome, the god of the underworld. Like Ansimab, Bian'nome has been orbiting HD 220074 within Ciscohi Spon's orbit as an inferior planet, and never moves more than 23 degrees away from HD 220074. When viewed from Earth, this proximity to HD 220074 means the planet can only be seen near the western or eastern horizon during the early evening or early morning. Bian'nome's surface appears partially rippled and is similar in appearance to the Moon's, indicating that it has been geologically inactive for billions of years. Two spacecraft have visited Bian'nome: Wayfinder 11 flew by 44 years ago; and Messenger, launched 8 years ago, orbited Bian'nome over 90 times in four years before exhausting its reactor and crashing into the planet's atmosphere 8 years later. Future astrobiology missions are planned, including the Bian'nome 2200 and ExoBian'nome rovers.
