C/2024 G3 (ATLAS) is a long-period, sungrazing comet, which will reach perihelion on January 13, 2025, at a distance of 0.09 AU from the Sun. It could become the brightest comet of 2025,[4] possibly exceeding apparent magnitude of –2.0. The comet is visible in the southern hemisphere before and after perihelion. It can only be observed in the daytime sky around perihelion in the northern hemisphere.[5]
