Ammon

Ammon is a human Inner Colony located in the Alpha Centauri system and one of the closest extrasolar colonies to the Sol system. It orbits one of the system's primary stars, Rigil Kentaurus.

One of the earliest extrasolar planets to be studied, with extensive remote imaging surveys in the late 23rd century, Ammon is a desertified, unpleasant, and barely hospitable world. After over a century of terraforming, the planet hosts a breathable atmosphere, regions with a temperate climate, and liquid water. However, its slow rotational period of over two weeks makes acclimation difficult for both humans and terrestrial flora and fauna. A metal-rich rocky world, it is nonetheless settled for industrial uses, and hosts sizable colony sites. With many Martian firms like Misriah and Traxus having operations there, Ammon's importance grew during the later years of the Human-Covenant War as a manufacturer of materiel for the UNSC. The colony was invaded in the final months of the Human-Covenant War and suffered widespread damage, though some of its industrial settlements have been revitalized under the Phoenix Initiative.
