URANO

Nella mitologia greca, Urano rappresenta il cielo stellato della sera. Urano venne fuori spontaneamente dalla Terra (personificata dalla dea Gea). Gea venne a sua volta spontaneamente alla vita da Caos, che precedette tutte le cose.

I SATELLITI DI URANO

	Uranus has 15 known moons. Unlike the other bodies in the solar system which have names from classical mythology, Uranus's moons take their names from the writings of Shakespeare and Pope. They form two distinct classes: the 10 small very dark inner ones discovered by Voyager 2 and the 5 large outer ones. They all have nearly circular orbits in the plane of Uranus's equator (and hence at a large angle to the plane of the ecliptic).
