Palamok
From Halopedia, the Halo wiki
Palamok is the Yanme'e homeworld. Its atmospheric composition is similar to that of Earth, yet inhospitable to humans. Palamok itself is quite Earthlike, although significantly larger and tending to tropical extremes. It is a flat and geologically featureless world, with little tectonic or volcanic activity. It has average surface temperatures of 29°C to 42°C (84.2°F to 107.6°F), and its gravity is two times that of Earth. This would present a challenge on the evolution of the wings of the Yanme'e, but it gives them excellent flight skills in the gravity of Earth.[1]
