Fictional info (?)
Suggested nameWair
Planet typeCold planet
In English, Wair is often referred to as the "green planet" because the carbon dioxide prevalent on its surface gives it a slight green appearance that is unusual among the astronomical bodies visible to the naked eye. Wair is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth. Wair is orbiting HD 8673 A every 1600 Earth days. It is the second-brightest natural object in the night sky after Gyushex, reaching an apparent magnitude of -5 - bright enough to cast shadows at night and, often, visible to the naked eye in broad daylight.

For this reason, scientists often classify Wair and Gyushex as "cold planets" to distinguish them from the other planets. The planet is named after the deity Wair, the bringer of nature.

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 8673 A, which reoccurs over the so-called synodic period approximately every 81 days.

Wair is primarily composed of oxygen with a significant part of its mass being carbon dioxide, though carbon dioxide comprises only about a small fraction of the number of molecules.
