Uranus, the Greek god of the Sky. The seventh planet out from the sun is a veritable twin of the next planet out, Neptune. Icy atmosphere: about 83% hydrogen, 15% helium, 2% methane - and trace ammounts of ammonia.

Uranus has at least 15 moons - five main orbital spheres ripe for mining and eventual suburban colonization: Oberon, Titania, Umbriel, Ariel and Miranda - and ten small enough to have eluded our attention until space probes were invented and sent to investigate: Cordelia, Ophelia, Bianca, Cressida, Desdemona, Juliet, Portia, Rosalind, Belinda and Puck.
