Gertrude (crater)

Gertrude /ˈɡɜːrtruːd/ is the largest known crater on Uranus's moon Titania. It is about 326 km across,[1] 1/5 of Titania's diameter.[lower-alpha 1] It is named after the mother of Hamlet in William Shakespeare's play Hamlet.[1] Features on Titania are named after female Shakespearean characters.

Gertrude is the large crater near the top of this Voyager 2 image.

The crater rim of Gertrude is elevated by 2 km over the crater floor. In the center of the crater there is a large dome, which resulted from the uplift of the surface immediately after the impact. The dome has the diameter of about 150 km and is 2–3 km high. The rim and dome are low for crater with such a large diameter indicating that the relief has relaxed since the impact. The surface of the dome has only few superimposed smaller craters, which means that it was modified later.[2]

Notes
  1. Other sources report the diameter of 400 ± 15 km.[2]
gollark: Or, well, shut down.
gollark: Wait, wiki.computercraft.cc is gone‽
gollark: It might be easier to just run CraftOS-PC under a really minimal Alpine install with X11 and such. Unless it can be made to write to framebuffers directly or something.
gollark: Increasing the floor height would make mountains less cool, which would be more of a problem if they were good in the first place.
gollark: One would hope so. Alternatively they could bodge it horribly with a cave dimension.
