    en.wikipedia.org/wiki/List_of_comets_by_type

    This is a list of comets (bodies that travel in elliptical, parabolic, and sometimes hyperbolic orbits and display a tail behind them) listed by type. Comets are sorted into four categories: periodic comets (e.g. Halley's Comet), non-periodic comets (e.g. Comet Hale–Bopp), comets with no meaningful orbit (the Great Comet of 1106), and lost comets (), displayed as either P (periodic), C (non ...

    The comet passed at a distance of 0.0982 astronomical units (14,690,000 km; 9,130,000 mi) from Earth on 4 July, making it the fourth closest known approach of a comet to Earth in the 19th century. [3] Consequently the comet moved away from both the Earth and the Sun, while brightening moonlight hampered observations.

    Jupiter-family comets and long-period comets appear to follow very different fading laws. The JFCs are active over a lifetime of about 10,000 years or ~1,000 orbits whereas long-period comets fade much faster. Only 10% of the long-period comets survive more than 50 passages to small perihelion and only 1% of them survive more than 2,000 ...

    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. It is potentially the brightest comet of 2025, [6] with an apparent magnitude reaching −3.8 on the day of its perihelion. [5] The comet is visible in the southern hemisphere before and after perihelion.

    Periodic comets usually have elongated elliptical orbits, and usually return to the vicinity of the Sun after a number of decades. The official names of non-periodic comets begin with a "C"; the names of periodic comets begin with "P" or a number followed by "P". Comets that have been lost or disappeared have names with a "D". Comets whose ...
