Newcomb Crater is an impact crater in the Sinus Sabaeus quadrangle of Mars, located at 24.4 °S latitude and 359.1 °W longitude. Newcomb is in the west of Noachis Terra and lies next to Margaritifer Terra. It is 252 km in diameter and was named after the American astronomer Simon Newcomb, and the name was approved in 1973 by the International Astronomical Union (IAU) Working Group for Planetary System Nomenclature (WGPSN).[1]
East of the crater is Marikh Vallis. Nearby named craters include Mädler further north, Wislicenus almost to the east, Bakhuysen to the east, the larger Dollfus (recently named in 2013), the large Greeley further south (recently named in 2015), further west are the small craters of Novara and Peta, and the smaller Beer to the northwest. A valley lies west of Newcomb and is recently named Bashkaus Valles.
Two smaller craters making up a crater pair are in the southwest part. Also in that area and running in the west area is the Martian Prime Meridian and west of it, that part of the crater is inside the Margaritifer Sinus quadrangle.
