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

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.
