Helmholtz Crater is an impact crater in the Argyre quadrangle on Mars at 45.8°S and 21.3°W and is 111.5 km in diameter. Helmholtz is located inside Noachis Terra just east of Argyre Planitia.[1] Its name was approved in 1973 by the International Astronomical Union (IAU) Working Group for Planetary System Nomenclature (WGPSN), and it was named after German physicist Hermann von Helmholtz (1821–1894).[2]

Description[edit]
Nearby prominent craters are the slightly larger Lohse over a crater diameter to the east-northeast, Wirtz to the southwest and Arkhangelsky further north-northwest. Further southeast is a small valley known as Frento Vallis.
Unlike its adjacent prominent craters, it has no central peak. Gullies dominate parts of the crater rim and inside the crater has sand dunes.
