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 ]
On Jan. 13, the comet is expected to reach perihelion (its closest point to the Sun). At this time, the comet will come within approximately 8.3 million miles of the Sun. The same day, it's also ...
Dwarf planet 90377 Sedna will reach its perihelion of 76 AU from the Sun. [34] 2079 August 11 Mercury occults Mars, the first since at least 1708. [31] 2083 A star system known as "V Sagittae" is expected to go nova this year (+/- 11 years). 2084 November 10 Transit of Earth as seen from Mars, the first and the only one in this century. 2085 ...

At perihelion, Earth is roughly 91.4 million miles away from the sun. On average, the planet is separated from the sun by a distance of approximately 93 million miles.
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.
