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]
The next perihelion of Halley's Comet is predicted for 28 July 2061, [4] [5] when it will be better positioned for observation than during the 1985–1986 apparition, as it will be on the same side of the Sun as Earth. [166] The closest approach to Earth will be one day after perihelion. [7]
C/2024 G3 (ATLAS) is a 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 comet reached its perihelion on Monday at 7:30 a.m. ET and was completely vaporized after passing within 1% of Earth’s distance from the sun, less than 1 million miles (1.5 million ...
Halley's Comet will be at perihelion during its following pass. [28] 2134 May 7 Halley's Comet will get within 13.9 million km (8.6 million mi) of Earth. [47] 2141 June 19 Long-duration lunar eclipse of about 106.1 minutes. This lunar eclipse is in the same Saros series (132) as the long lunar eclipse in 2123, and has an almost identical ...
A recently discovered comet, named C/2023 A3 Tsuchinshan–ATLAS, makes its closest approach of Earth on Saturday. The comet’s next appearance may be in 80,000 years.
Periodic comets (also known as short-period comets) are comets with orbital periods of less than 200 years or that have been observed during more than a single perihelion passage [1] (e.g. 153P/Ikeya–Zhang). "Periodic comet" is also sometimes used to mean any comet with a periodic orbit, even if greater than 200 years.
The comet passed perihelion on 8 July. C. S. Morris reported the comet on 15 July had a tail 50 arcminutes long with two components. [5] The comet faded in August as it moved both away from Earth and the Sun and by the end of the month its magnitude was reported to be around 10. The comet continued to fade slowly and was reported to be mag. 13.
