The diagram illustrates the orbits of those irregular moons discovered so far.

They are believed to have formed in orbit about their primary, as opposed to irregular moons, which were captured.

All the irregular moons are probably captured objects that were trapped by Uranus soon after its formation.

Saturn, Uranus and Neptune also have some irregular moons, which orbit far from their respective planets.

In astronomy, an irregular moon is a natural satellite following a distant, inclined, and often eccentric and retrograde orbit.

Uranus's irregular moons have elliptical and strongly inclined (mostly retrograde) orbits at great distances from the planet.

The largest of the irregular moons is Phoebe, the ninth moon of Saturn, and was discovered at the end of the 19th century.

Uranus was the last giant planet without any known irregular satellites, but since 1997 nine distant irregular moons have been identified using ground-based telescopes.

Irregular moons are small satellites with large-radii, inclined, and frequently retrograde orbits, believed to have been acquired by the parent planet through a capture process.

After Phoebe, Ymir is the largest of the known retrograde irregular moons, with an estimated diameter of only 18 km.

Uranian moons are divided into three groups: thirteen inner moons, five major moons, and nine irregular moons.
