Minerva

Minerva is the smallest of Al'Ard's two moons, but also the most geologically active and potentially habitable. It's lower albedo means that it was only recognized as a moon after the invention of telescopes. It is unknow exactly why it's geological activity persists despite its small size, and has been theorized to have been a rogue planetary body caught by Al'Ard's gravity after its formation by a large impact event elsewhere in the solar system. While it's atmosphere, volcanism, and electromagnetic field, and much more moderate temperature, make it more appealing for exploration, evidence also suggests it is far less resource rich.
In 1977 two Exonauts from the Federal Vanguardist Rael Commonwealth, and one the Republic of Getzi visited during COMSET's Desert Falcon 1 Minerva Mission, marking the first humans to set foot on the body, and the second manned mission to set foot on any celestial body outside of Al'Ard.
