Baranamtarra is a 25.5 km diameter crater on the surface of Venus.[1] The crater is proximate to the Zverine Chasma, along with Montez, Wheatley, and Kono Mons.[2][3]
Geology and characteristics
[edit]Baranamtarra has a diameter of 25.5 km,[1] with a continuous ejecta radius of 14 km and a wall width of 2.2 km.[4] The crater is highly embayed by the volcanic flows and is fractured,[5][6] which is extremely rare for a crater since only 12% of craters are fractured, and approximately 2.5% of craters that are embayed by lava.[7] The crater can be located at the coordinates 16°36′N 268°00′E / 16.6°N 268.0°E.
Naming
[edit]Baranamtarra's name derives from the Mesopotamian queen named Baranamtarra, which was approved by the IAU in the year 1994.[1] On Venus, they are named after deceased women who have made outstanding or fundamental contributions to their field if the crater is over 20 km in diameter.[3]
