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...

Halley's Comet is the only known short-period comet that is consistently visible to the naked eye from Earth, appearing every 72–80 years. It last appeared...

In astronomy, the ecliptic coordinate system is a celestial coordinate system commonly used for representing the apparent positions, orbits, and pole orientations...

1822. Comets are in unstable orbits that evolve over time due to perturbations and outgassing. Given Encke's low orbital inclination near the ecliptic and...

ecliptic comets) and long-period comets (also called nearly isotropic comets). Ecliptic comets have relatively small orbits aligned near the ecliptic plane...

Comet Hale–Bopp (formally designated C/1995 O1) is a comet that was one of the most widely observed of the 20th century and one of the brightest seen for...

orbital eccentricity of 3.36 and is not bound to the Sun. The comet passed through the ecliptic of the Solar System at the end of October 2019, and made its...

an Encke-type comet. Short-period comets with orbital periods less than 20 years and low inclinations (up to 30 degrees) to the ecliptic are called traditional...

ecliptic comets. However, studies of the region since 1992 have shown that the orbits within the Kuiper belt are relatively stable, and that ecliptic...

at maximum southern ecliptic latitude (just under 14 degrees of arc). The position of comet C/2023 A3 in October 2024. The comet is located in the southernmost...

Comet Kohoutek (formally designated C/1973 E1 and formerly as 1973 XII and 1973f) is a comet that passed close to the Sun towards the end of 1973. Early...

Comet Hyakutake (formally designated C/1996 B2 (Hyakutake)) is a comet discovered on 31 January 1996. It was dubbed the Great Comet of 1996; its passage...

to the Sun, it showed no signs of having a coma, the usual nebula around comets formed when they pass near the Sun. Further, it exhibited non‑gravitational...

above and below the ecliptic. By extension, the "zodiac of the comets" may refer to the band encompassing most short-period comets. As early as the 14th...

a periodic comet with an orbital period of 71 years. Comets with an orbital period of 20–200 years are referred to as Halley-type comets. It is one of...
