first soft landing on a comet (November 2014) Notes: (a) Due to a non-spherical, irregular shape, a comet's x, y, and z axes instead of an (average) diameter are often used to describe its dimensions. (b) Closest approach given in multiples of the comet's (average mean) radius · List ordered in ascending order by a comet's first visit.
C/2024 G3 (ATLAS) is a partially disintegrated non-periodic comet, which reached perihelion on 13 January 2025, at a distance of 0.09 AU (13 million km) from the Sun.It is currently the brightest comet of 2025, [6] with an apparent magnitude reaching −3.8 on the day of its perihelion. [5]

C/2001 Q4 (NEAT) is a comet with an almost perpendicular retrograde orbit which brings it into the inner Solar System by a deeply southward path. [2] It initially emerged from its remote home spending most of its time near the south celestial pole. This comet was discovered on August 24, 2001 by the Near-Earth Asteroid Tracking program (NEAT).
In comet nomenclature, the letter before the "/" is either "C" (a non-periodic comet), "P" (a periodic comet), "D" (a comet which has been lost or has disintegrated), "X" (a comet for which no reliable orbit could be calculated — usually historical comets), or "A" for an object that was mistakenly identified as a comet, but is a minor planet.

C/2024 S1 (ATLAS) (previously had the temporary designation A11bP7I) was a sungrazing comet that was discovered from the 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.
