List of periodic comets - Wikipedia
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.

Short-period - or periodic comets - are comets which take less than 200 years to orbit the Sun, though some may only take a few years or decades. They have much smaller orbits than long-period comets - whose orbits might last a million years.

These icy objects, occasionally pushed by gravity into orbits bringing them closer to the Sun, become the so-called short-period comets. Taking less than 200 years to orbit the Sun, in many cases their appearance is predictable because they have passed by before.
Short Period Comets - an overview | ScienceDirect Topics
1976年3月9日 · Short period comets are comets that have relatively short orbital periods, such as Comet Encke with a period of 3.3 years. These comets can be predicted and some can be observed throughout their entire orbits, often having their aphelia close to Jupiter's orbit.

The following table lists the major periodic comets in our solar system. Periodic comets, also called short-period comets, have orbital periods of less than 200 years or which have been observed during at least one perihelion passage.

To determine which objects to include in the list, we adopt the IAU definition for short-period comets. This includes all numbered periodic comets (those observed on at least two apparitions) and unnumbered comets whose orbital periods have been determined to be less than 200 years.

2024年10月2日 · They are “hybrid” in the sense that they are in a transitional stage of their orbital evolution: Many share characteristics with both trans-Neptunian objects (from the cold Kuiper Belt reservoir), and short-period comets, which are objects highly altered by repeated close passages around the Sun.

Short-period comets typically have orbital periods ranging from 3 to 200 years, with the majority having periods of less than 20 years. These comets are believed to originate from the Kuiper Belt, a region of icy objects beyond the orbit of Neptune.
