C/2024 L5 (ATLAS) is a comet that was discovered on 14 June 2024 as A117uUD by the Asteroid Terrestrial-impact Last Alert System (ATLAS), South Africa, Sutherland. It will reach perihelion on 10 March 2025 at 3.432 AU (513.4 million km) from the Sun.[4][5] It is the second known Solar System comet to become interstellar after experiencing a planetary encounter.[5][1] C/1980 E1 (Bowell) reached a hyperbolic trajectory after an encounter with Jupiter on 9 December 1980.[6][7] C/2024 L5 (ATLAS) experienced a very close encounter at 0.0048 AU with Saturn on 24 January 2022.[2][5][1]
