Suggested nameYatochu Nu
Planet typeCold planet
It is the second-brightest natural object in the night sky after Hyogobya Ke, reaching an apparent magnitude of -5 - bright enough to cast shadows at night and, rarely, visible to the naked eye in broad daylight.

It is named after the deity Yatochu Nu, the goddess of good fortune.

It has the densest atmosphere of all the cold planets, consisting primarily of carbon monoxide.

Yatochu Nu is primarily composed of carbon monoxide with a significant part of its mass being 2H2O, though 2H2O comprises only about a tiny fraction of the number of molecules.
