Gertrude /ˈɡɜːrtruːd/ is the largest known crater on Uranus's moon Titania. A peak-ring impact basin, it is roughly 326–400 kilometers across,[1][2] 1/5 to 1/4 of Titania's diameter.[a] Gertrude was first observed by the Voyager 2 spacecraft on its January 1986 flyby of the Uranian system. It is named after Gertrude, the mother of Prince Hamlet in William Shakespeare's play Hamlet. The name Gertrude was officially adopted by the International Astronomical Union (IAU) in 1988.[1] Features on Titania are named after female Shakespearean characters.
