Coin showing Caesar's Comet as a star with eight rays, tail upward. Non-periodic comets are seen only once. They are usually on near-parabolic orbits that will not return to the vicinity of the Sun for thousands of years, if ever.
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 ...
In comet nomenclature, the letter before the "/" is either "C" (a non-periodic comet), "P" (a periodic comet), "D" (a comet which has been lost or has disintegrated), "X" (a comet for which no reliable orbit could be calculated — usually historical comets), or "A" for an object that was mistakenly identified as a comet, but is a minor planet.
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 was reported to have a nuclear shadow, a dark lane in the tail, and was marginally visible with naked eye on that day. [10] On 7 January the comet was reported to be of first magnitude, with a tail about 20 arcminutes long. [5] The comet was photographed by cosmonaut Ivan Vagner onboard the International Space Station on 10 January. [11]
60P/Tsuchinshan, also known as Tsuchinshan 2, is a periodic comet in the Solar System with an orbital period of 6.79 years. [5] Tsuchinshan is the Wade-Giles transliteration corresponding to the pinyin Zǐjīn Shān 紫金山, which is Mandarin Chinese for "Purple Mountain".
