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 ...
Baldridge estimated the comet at magnitude −1. [8] The comet's discoverer, Terry Lovejoy, made a pair of observations on 17 December at 01:12 and 20:24 UTC, with apparent magnitudes estimated at −1.2 and −0.8, respectively. [8] Images taken on 20 December around 08:00 UTC suggested that the comet had undergone significant changes.
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 ...
What is comet C/2023 A3? The approach of Comet Tsuchinshan–ATLAS has particularly excited astronomers because it is a long-period comet, meaning the comet takes more than 200 years — or 80,000 ...

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.
