Another satellite, Perdita, was discovered in 1999 [10] by Erich Karkoschka after studying old Voyager photographs. [11] Uranus was the last giant planet without any known irregular moons until 1997, when astronomers using ground-based telescopes discovered Sycorax and Caliban.

Retrograde irregular satellites of Uranus. Ferdinand is the most distant known satellite of Uranus. It follows a retrograde, modestly inclined but highly eccentric orbit. The diagram illustrates the orbital parameters of the retrograde irregular satellites of Uranus (in polar co-ordinates) with the eccentricity of the orbits represented by the segments extending from the pericentre to the ...
Francisco is the innermost irregular satellite of Uranus. Francisco was discovered by Matthew J. Holman, et al. and Brett J. Gladman, et al. in 2003 from pictures taken in 2001 and given the provisional designation S/2001 U 3. Confirmed as Uranus XXII, it was named after a lord in William Shakespeare's play The Tempest. [8]
