Venus is the second planet from the Sun. It is sometimes called Earth's "sister" or "twin" planet as it is almost as large and has a similar composition. As an interior planet to Earth, Venus (like Mercury) appears in Earth's sky never f ...

Named after
Artemis
In ancient Greek mythology and religion, Artemis (; grc-gre, Ἄρτεμις) is the goddess of the hunt, the wilderness, wild animals, nature, vegetation, childbirth, care of children, and chastity. She was heavily identified wit ...
, the goddess of hunting, it is the largest corona on Venus, with a diameter of 2,600 kilometers. It is largely enclosed by the near circular
Artemis Chasma - a circular belt of arc-shaped features believed to be largely of compressional origin.
It was first described in 1980.
Artemis is an unusual feature on Venus as it has been interpreted to be the site of plate tectonics operating on a regional scale.
[Spencer, J. E. (2001) ''Possible giant metamorphic core complex at the center of Artemis Corona, Venus,'' Geological Society of America Bulletin 113(3), 333-345.] There are grabens and compressional arcs which rise above the surrounding plains. As a whole, Artemis is not elevated like other coronae. Regions within Artemis are in fact some 4 km below the surrounding plains. The differences between the highest and the lowest point within Artemis are in the order of 7.5 km.
The central rift region of Artemis has been interpreted as a spreading zone (Britomartis Chasma) which has been offset - with clear signs of strike-slip faulting offsetting the central rift zone. Retrograde subduction is interpreted to occur at the circular arc belts of Artemis Chasmata.
