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]
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. Dubbed the Great Comet of 2025 , it is currently the brightest comet of 2025, [ 6 ] with an apparent magnitude reaching −3.8 on the day of its perihelion. [ 5 ]

The apsides refer to the farthest (2) and nearest (3) points reached by an orbiting planetary body (2 and 3) with respect to a primary, or host, body (1). An apsis (from Ancient Greek ἁψίς (hapsís) 'arch, vault'; pl. apsides / ˈ æ p s ɪ ˌ d iː z / AP-sih-deez) [1] [2] is the farthest or nearest point in the orbit of a planetary body about its primary body.
Common orbital subgroups of Near-Earth Objects (NEOs). Atira asteroids / ə ˈ t ɪr ə / or Apohele asteroids, also known as interior-Earth objects (IEOs), are Near-Earth objects whose orbits are entirely confined within Earth's orbit; [1] that is, their orbit has an aphelion (farthest point from the Sun) smaller than Earth's perihelion (nearest point to the Sun), which is 0.983 astronomical ...
For Earth's current orbital eccentricity, incoming solar radiation varies by about 6.8%, while the distance from the Sun currently varies by only 3.4% (5.1 million km or 3.2 million mi or 0.034 au). [11] Perihelion presently occurs around 3 January, while aphelion is around 4 July.
An outer Earth-grazer asteroid is an asteroid that is normally beyond Earth's orbit, but which can get closer to the Sun than Earth's aphelion (1.0167 AU), and not closer than Earth's perihelion (0.9833 AU); i.e., the asteroid's perihelion is between Earth's perihelion and aphelion. Outer Earth-grazer asteroids are split between Amor and Apollo ...
