Moons: Umbriel, Titania, Puck, Oberon, Ariel, Cressida, Desdemona,
Did you know: At magnitude 5.3, Uranus is just within the brightness scale that a human eye can perceive. 

Uranus The seventh planet from the sun, Uranus is an oddball. It’s the only giant planet whose equator is nearly at right angles to its orbit — it basically orbits on its side. Astronomers think the planet collided with some other planet-size object long ago, causing the tilt. The tilt causes extreme seasons that last 20-plus years, and the sun beats down on one pole or the other for 84 Earth-years. Uranus is about the same size as Neptune. Methane in the atmosphere gives Uranus its blue-green tint. It has numerous moons and faint rings.
