Proteus is heavily cratered, showing no sign of any geological modification.<ref name="SmithSoderblom1989" /> The largest crater, Pharos, has a diameter from {{nowrap|230 to 260 km}}.<ref name="Croft1992" /> Its depth is about 10–15&nbsp;km.<ref name="Stooke1994" /> The crater has a central dome on its floor a few kilometres high.<ref name="Stooke1994" /> Pharos is the only named surface feature on this moon. In [[Greek mythology]], it refers to the [[Lighthouse of Alexandria|island]] where Proteus reigned.<ref name="usgsPharos" /> In addition to Pharos, there are several craters 50–100&nbsp;km in diameter and many more with diameters less than 50&nbsp;km.<ref name="Stooke1994" />

Other [[landforms]] on Proteus include linear features such as [[Cliff|scarps]], valleys, and grooves. The most prominent one runs parallel to the equator to the west of Pharos. These features likely formed as a result of the giant impacts, which formed Pharos and other large craters or as a result of [[tidal force|tidal stresses]] from Neptune.<ref name="Stooke1994" /><ref name="Croft1992" />
