Encyclopedia
Otbah is an impact crater
on the southern hemisphere of Saturn
's moon Enceladus
. Otbah was first observed in Cassini images during that mission's March 2005 flyby of Enceladus. It is located at 39.6° South Latitude
, 156.0° West Longitude
, and is 9.2 kilometers across. A smaller impact occurred after the Otbah impact on the larger crater's southern rim, forming an impact crater 3 kilometers across. In addition to subsequent cratering, southwest-northeast trending fractures, prevalent in this region of Enceladus, cut across Otbah, forming several canyons several hundred meters deep along Otbah's rim. The high level of tectonic activity associated with this fracturing and the formation of the nearby south polar terrain may have also led to mass wasting along the crater's wall, leading to a 3 kilometer wide landslide deposit in the center of Otbah.
Otbah is named after one of the main characters in the tale "Otbah and Rayya" from The Book of One Thousand and One Nights
. A crater named after the other main character, Rayya
, is nearby.

Enceladus (moon)
Enceladus is the sixth-largest of the moons of Saturn. It was discovered in 1789 by William Herschel. Until the two Voyager spacecraft passed near it in the early 1980s very little was known about this small moon besides the identification of water ice on its surface...

Latitude
In geography, the latitude of a location on the Earth is the angular distance of that location south or north of the Equator. The latitude is an angle, and is usually measured in degrees . The equator has a latitude of 0°, the North pole has a latitude of 90° north , and the South pole has a...
