Planet Smogg

''"Smogg" redirects here. For the former government of the planet, see Kingdom of Smogg''

Planet Tsar Cupra 1b, known locally as Smogg [šmɔg] (Smogga: Planeta Schmogga [planεta šmɔga]), is the only terrestrial planet in the Tsar Cupra solar system. It is the largest known terrestrial planet in the Milky Way Galaxy. Smogg has 6 natural satellites.

Smogg has extensive plant life, including trees, and a diverse animal kingdom, consisting mainly of arthropoids. Photosynthetic plants and bacteria have created an atmosphere of about 32% oxygen, making Smogg an ideal planet for colonization by obligate aerobic life forms.

About 3% of the planet's surface has been colonized by extraterrestrial life forms, including scyphers, humans, Rigelians, Sfendians, and Gleisians. The high gravity of Smogg necessitates the use of artificial gravity fields, which is a limiting factor to colonial expansion.

Planet Smogg and its satellites were ruled as the Kingdom of Smogg before being overthrown and annexed by the Atarian Empire.
