Ahuna Mons,[2] formerly referred to as the pyramid-shaped mountain on Ceres,[3] is a large mountain that protrudes above otherwise smooth terrain on the dwarf planet and asteroid Ceres. Its nature is unknown: it is not an impact feature and it appears to be the only mountain of its kind on Ceres. Bright streaks run top to bottom on its slopes; these streaks are thought to be salt, similar to the better known Cererian bright spots.,[4] and likely resulted from cryovolcanic activity from Ceres's interior.[5] It is named after the traditional post-harvest festival Ahuna of the Sumi Naga people of India.
The mountain was discovered on images taken by the Dawn spacecraft in orbit around Ceres in 2015.[6] It is estimated to be about 6 km (4 mi or 20,000 ft) high[1] and 15 km (10 mi) wide at the base.[7]
