List of Uranus moons
The following table contains the most important data of all 27 natural satellites of Uranus known to date . Current new discoveries have a provisional numerical code until they are confirmed by the International Astronomical Union .

An orbit inclination of more than 90 ° means that the satellite is orbiting Uranus in reverse. As a rule, moons move around the planet in the same direction of rotation as the planet rotates around its own axis.

Naming
Almost all of Uranus' moons are named after people from plays by William Shakespeare :
- A Midsummer Night's Dream : Titania, Oberon, Puck
- The Tempest (Shakespeare) : Miranda, Caliban , Prospero, Trinculo, Francisco, Ferdinand, Stephano, Setebos and Sycorax
- King Lear : Cordelia
- Hamlet : Ophelia
- The Taming of the Shrew : Bianca
- Othello : Desdemona
- Romeo and Juliet : Juliet
- The merchant of Venice : Portia
- As you like it : Rosalind
- Much Ado About Nothing : Margaret
- The winter fairy tale : Perdita
- Troilus and Cressida : Cressida
- Timon of Athens : Cupid
Three of Uranus' moons are named after people from The Rape of the Lock , a poem by Alexander Pope : Ariel (also featured in Shakespeare's The Tempest ), Umbriel, and Belinda.
diagram
The diagram shows the orbital half-axes of the outer Uranus moons (abscesses, in million km) against their orbital inclination (ordinate, in degrees): The circle sizes do not show the relative lunar radii to the orbital elements. The horizontal lines represent the area between perihelion and aphelion of the respective lunar orbit.
