Pharos /ˈfɛərɒs/ is a crater on Neptune's moon Proteus. It is named after the Lighthouse of Alexandria, also known as the Pharos of Alexandria.[1] It is currently the only named surface feature on any irregularly shaped moon of Neptune. It measures 10–15 km deep and has a diameter of around 250 km (160 mi) in diameter, making it more than half the diameter of Proteus itself.[2] The impact that created Pharos may have also created Hippocamp, due to how unusually close it is to Proteus.[3]
