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 ...

Two elements define the shape and size of the ellipse: Eccentricity (e) — shape of the ellipse, describing how much it is elongated compared to a circle (not marked in diagram). Semi-major axis (a) — half the distance between the apoapsis and periapsis. The portion of the semi-major axis extending from the primary at one focus to the ...
Comet C/2022 E3 (ZTF) aka "The Green Comet" is making its closest approach to the Earth today. The moon is bright tonight, making it difficult to find the comet with the naked eye.
In comet nomenclature, the letter before the "/" is either "C" (a non-periodic comet), "P" (a periodic comet), "D" (a comet that has been lost or has disintegrated), "X" (a comet for which no reliable orbit could be calculated —usually historical comets), "I" for an interstellar object, or "A" for an object that was either mistakenly ...
You have just a few weeks left to view the "comet of the century" making its 80,000-year orbit around Earth. Comet C/2023 A3 Tsuchinshan–ATLAS will be visible with the naked eye from Earth until ...
A minor meteor shower, the Andromedids, occurs annually in November, and it is caused when Earth crosses the orbit of Biela's Comet. [156] Some comets meet a more spectacular end – either falling into the Sun [157] or colliding with a planet or other body. Collisions between comets and planets or moons were common in the early Solar System ...
