Cupid is one of the inner moons of Uranus, so small and dark that it escaped the notice of Voyager 2 during the spacecraft's visit in 1986. Little is known about it.
Cupid was discovered on 25 August 2003 by M.R. Showalter and J.J. Lissauer, using the Hubble Space Telescope.
How Cupid Got its Name:
Originally called S/2003 U2, Cupid was named for the Roman god of love, who appears in William Shakespeare's play, "Timon of Athens" (in keeping with the custom of naming most of Uranus' moons after Shakespearean characters).
Moons of Uranus are named for characters in Shakespeare's plays and from Alexander Pope's "Rape of the Lock."
