Comet Tago–Sato–Kosaka, formally designated as C/1969 T1, is a non-periodic comet that became visible in the naked eye between late 1969 and early 1970. [5] It was the first comet ever observed by an artificial satellite.
Comet Humason, formally designated C/1961 R1 (a.k.a. 1962 VIII and 1961e), was a non-periodic comet discovered by Milton L. Humason on September 1, 1961. Its perihelion was well beyond the orbit of Mars, at 2.133 AU. The outbound orbital period is about 2,516 years. The diameter of its comet nucleus is estimated at 30−41 km. [2]
C/ indicates a non-periodic comet i.e. any comet that is not periodic according to the preceding definition. X/ indicates a comet for which no reliable orbit could be calculated (generally, historical comets). D/ indicates a periodic comet that has disappeared, broken up, or been lost. [5]
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 ...

Comet Bennett, formally designated as C/1974 V2, is a non-periodic comet that was seen in 1974. During its most recent perihelion, the comet was observed to split apart and disintegrate. During its most recent perihelion, the comet was observed to split apart and disintegrate.
It has the systematic designation C/2020 F3, indicating a non-periodic comet which was the third discovered in the second half of March 2020. Comet NEOWISE made its closest approach to the Sun (perihelion) on July 3, 2020, at a distance of 0.29 AU (43 million km; 27 million mi).
