Bosporos Planum
Planum on Mars
Bosporos Planum is a high plateau (planum) located in the Thaumasia quadrangle in the Southern Hemisphere of Mars. It is about 730 km long stretching from southwest to northeast. Previously named Erythraeum Planum,[1] it was renamed to its current name in 1979.[2] Its name derives from one of the classical albedo features observed by early astronomers, named after the Bosphorus Strait.[2]
