Apollo And His Muses Picture

This is Apollo, a gas giant about three times the size of Jupiter (though it has just about the same density). It orbits closer to its star than the gas giants of our system, close enough that some of the moons orbiting it are habitable. There are nine major moons, each named after one of the muses; Calliope, Clio, Erato, Euterpe, Melpomene, Polyhymnia, Terpsichore, Thalia (not pictured), and Urania. Two of the moons, Urania and Clio (named after the muses of astronomy and history respectively), are inhabited. Clio (in the background) is roughly the size of Earth, and has a large ecosystem produced by natural evolution. Humans have recently begun to settle there, though there is some debate as to the level of intelligence displayed by some of the natives species. Urania (in the foreground), on the other hand, has been terraformed and settled by humans, who collect valuable hydrogen fuel from Apollo's atmosphere and minerals from other orbiting bodies.

The storm on Apollo isn't quite like Jupiter's Great Red Spot. The Eye of Apollo, as it is called, will start and stop in increments that change as the planet orbits the planet (making it appear to change with the seasons). The only other planet in the system, a gas giant named Artemis, is only slightly larger than Jupiter. It has a moon, Orion, which has a natural ecosystem of carbon-methane based bacteria. It also displays an impressive ring, though it pales in comparison to Saturn.
