Suggested nameBosnar Io
Planet typeCold planet
When viewed from Maaephaë Her, Bosnar Io can reach an apparent magnitude of -3, bright enough for its reflected light to cast shadows, and making it on average the third-brightest object in the night sky. The planet is named after the deity Bosnar Io, the spirit of chaos.

It may have had carbonyl sulfide oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.

Bosnar Io is primarily composed of hydrogen chloride with a significant part of its mass being krypton, though krypton comprises only about a limited fraction of the number of molecules. A prominent result is the "great brown spot", a giant storm that is known to have existed for centuries since it was first detected by scanner.
