Dimensions. ~5 km (3 mi) [ 1] C/2020 F3 (NEOWISE) or Comet NEOWISE is a long period comet with a near-parabolic orbit discovered on March 27, 2020, by astronomers during the NEOWISE mission of the Wide-field Infrared Survey Explorer (WISE) space telescope. At that time, it was an 18th-magnitude object, located 2 AU (300 million km; 190 million ...
62P/Tsuchinshan. 62P/Tsuchinshan, also known as Tsuchinshan 1, is a periodic comet first discovered January 1, 1965 at the Purple Mountain Observatory in Nanking. [6] It last came to perihelion on 25 December 2023 at around apparent magnitude 8, [2] and was then 0.53 AU (79 million km) from Earth and 110 degrees from the Sun. [4]
List of periodic comets. 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.
Comet E3 will be found between the Big Dipper and the Little Dipper in the final nights of January leading up to its closest encounter with the Earth on Feb. 1. It will appear stationary in the ...

C/2019 Y4 (ATLAS) (or Comet ATLAS) was a comet with a near-parabolic orbit discovered by the ATLAS survey on December 28, 2019. [3] Early predictions based on the brightening rate suggested that the comet could become as bright as magnitude 0 matching the brightness of Vega. [4] It received widespread media coverage due to its dramatic increase ...
2.1 (in 1986) [ 14] 28.2 (in 2003) [ 15] Halley's Comet is the only known short-period comet that is consistently visible to the naked eye from Earth, [ 16] appearing every 72–80 years. [ 17] It last appeared in the inner parts of the Solar System in 1986 and will next appear in mid-2061. Officially designated 1P/Halley, it is also commonly ...
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 ...
