Eayn

Eayn is the Jackal homeworld and a satellite orbiting the planet Chu'ot‎. The gravity is about 0.875 G's, making the inhabitants lighter on Eayn than on Earth. This is surprising, considering how swiftly Jackals move on Earth. Eayn's atmosphere is composed of oxygen, nitrogen, and Carbon Dioxide (very similar to Earth), with a surface temperature ranging from -18°C to 45°C (-0.4F to 113F). Another similarity to the humans' homeworld is the temperature, which is only the smallest bit warmer. This means than Eayn is approximately the same distance from Y'Deio as Earth is from Sol.

This planet lies within the inner region of the system's massive asteroid belt. The worlds surface was characterized by a single large ocean, sparse volcanic activity and an almost total lack of glacification. About one third of the Kig-yar population in the Y'Deio system called the satellite their home. The remaining Jackals chose to set up colonies within the asteroid belt even before their discovery by the Covenant.

Trivia
