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 ...
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.
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.
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 ...
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 ...
The comet will be above Venus, which is the brightest "star" in the sky, and slightly to the planet's right. ... If it will be cloudy all night, for example, you may want to plan for another ...
Look up into the sky this month and you might see a rare comet that won’t return for tens of thousands of years. Comet Tsuchinshan-ATLAS, also known as C/2023 A3 to scientists and pronounced ...
The following list is of comets with very long orbital periods, defined as between 200 and 1000 years.These comets come from the Kuiper belt and scattered disk, beyond the orbit of Pluto, with possible origins in the Oort cloud for many.
