The Great Comet of 1577 is a well-known example of a great comet. It passed near Earth as a non-periodic comet and was seen by many, including well-known astronomers Tycho Brahe and Taqi ad-Din. Observations of this comet led to several significant findings regarding cometary science, especially for Brahe.
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 ...
Prefixes are then added to indicate the nature of the comet: P/ indicates a periodic comet, defined for these purposes as any comet with an orbital period of less than 200 years or confirmed observations at more than one perihelion passage. [5] C/ indicates a non-periodic comet i.e. any comet that is not periodic according to the preceding ...
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 ...

The Great Comet of 1577 (designated as C/1577 V1 in modern nomenclature) [4] is a non-periodic comet that passed close to Earth with first observation being possible in Peru on November 1 1577. [5] Final observation was made on January 26, 1578.
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 years in this case ...
Comets which do not fulfill the "periodic" requirements receive the "C" prefix (e.g. C/2006 P1, the Great Comet of 2007). Comets initially labeled as "non-periodic" may, however, switch to "P" if they later fulfill the requirements. Comets which have been lost or have disintegrated are prefixed "D" (e.g. D/1993 F2, Comet Shoemaker-Levy 9).
