It will reach perihelion on 10 March 2025 at 3.432 AU (513.4 million km) from the Sun. [4] [5] It is the second known Solar System comet to become interstellar after experiencing a planetary encounter. [5] [1] C/1980 E1 (Bowell) reached a hyperbolic trajectory after an encounter with Jupiter on 9 December 1980.
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 ]
Comet G3 ATLAS (C/2024) is predicted to be visible from parts of Earth throughout the month. On Jan. 13, the comet is expected to reach perihelion (its closest point to the Sun).
Comet Swift–Tuttle (source of the Perseids) comes to perihelion. [44] 2126 July 29 At 16:08 UTC, Mercury will occult Mars. [31] [42] [45] 2130 March 10 At 07:32 UTC, Sun passes through the Solar System barycenter. [46] 2133 December 3 At 14:10 UTC, Mercury will occult Venus. [31] [42] 2134 March 27 Halley's Comet will be at perihelion during ...
A bright comet could be visible in skies across the globe over the coming days for the first time in 160,000 years. Nasa said the future brightness of a comet is "notoriously hard" to predict, but ...
3-Point Contest Saturday, 8 p.m. ET (TNT) This year's field includes two-time reigning 3-point champion , Damian Lillard, who is also among five 2025 All-Stars competing in the shootout.
21P/Giacobini-Zinner will next pass perihelion on 25 March 2025, and will have its closest approach to Earth 4 days before, on 21 March. It is expected to brighten to magnitude ~11. [ 9 ]
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.
