C/2024 S1 (ATLAS) (previously had the temporary designation A11bP7I) was a sungrazing comet that was discovered by ATLAS-HKO in Hawaii on 27 September 2024. The comet passed its perihelion on 28 October 2024, at a distance of about 0.008 AU (1.2 million km; 0.74 million mi) from the barycenter of the Solar System,[1] and disintegrated. The comet had a similar orbit to the Kreutz sungrazers, which were created by the fragmentation of a large comet.
