Addams is an 87 km diameter impact crater on Venus,[1] located on the eastern flank of the Triglava Corona,[2] and is on the surface of Laimdota Planitia.[3] It was named after American social worker Jane Addams,[4] which was adopted by the International Astronomical Union in the year 1994.[1] The bright outflow deposits from this oblique impact extend 600 km from the crater rim.[5] This is the largest outflow deposit for any Venusian crater,[6] and it has been compared to a mermaid in form.[7] The material from this fluidized ejecta blanket likely lies on the down-trajectory side of the impact.[5][8][9][7] It has a continuous ejecta radius of 68 km, and a wall width of 9.5 km.[10]
Formation
[edit]Addams formed from an asteroid crashing onto the northwest surface of Venus, forming a crater basin with an ejecta blanket stretching across three quarters of the crater rim. In addition, the impact-melt ejecta and lava molten flowed downhill for about 370 miles (600 km) east from the impact crater, forming the tail.[11][9]
