Francisco is the closest non-spherical moon of Uranus.
Francisco was found by Matthew J. Holman, et al. and Brett J. Gladman, et al. in 2003 from pictures taken in 2001 and given the designation S/2001 U 3. Confirmed as Uranus XXII, it was named after a lord in William Shakespeare's play The Tempest.
