Crater on Saturn's moon Enceladus
Dunyazad
is a large
crater
on
Saturn
's moon
Enceladus
first discovered by the
Voyager 2
spacecraft. It is named after
Dunyazad
, the sister of
Scheherazade
in
The Book of One Thousand and One Nights
.
Dunyazad is located at
41°54′N
200°36′W
/
41.9°N 200.6°W
/
41.9; -200.6
[1]
and is approximately 31 kilometers across, making it one of the largest craters on Enceladus. It is the southernmost crater of a prominent crater triplet on Enceladus' anti-Saturnian hemisphere (there is no evidence that the impacts are related or were formed from break-up of a single body, like
Shoemaker-Levy 9
). The craters to its north are
Shahrazad
, and
Al-Haddar
.
[2]
Voyager 2
discovery images
of this crater revealed an up-domed floor at Dunyazad, suggesting that the crater had been modified by viscous relaxation. Higher resolution views of Dunyazad taken by the
Cassini
Spacecraft
during a close flyby on March 9, 2005 reveal not only an up-domed floor, but numerous tectonic fractures as well, particularly within the dome and northeastern crater rim.
