C/2022 E3 (ZTF) C/2022 E3 (ZTF) is a non-periodic comet from the Oort cloud that was discovered by the Zwicky Transient Facility (ZTF) on 2 March 2022. [ 1] The comet has a bright green glow around its nucleus, due to the effect of sunlight on diatomic carbon and cyanogen. [ 6][ 5] The comet's systematic designation starts with C to indicate ...

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.
Anthony Cuthbertson,Graeme Massie and Vishwam Sankaran. February 2, 2023 at 8:18 PM. A green comet is flying past Earth for the first time in 50,000 years, offering skygazers a one-off opportunity ...
0.869 AU (130.0 million km) Comet total. magnitude (M1) 6.9. C/2021 T4 (Lemmon) is an inbound long period comet discovered by the Mount Lemmon Observatory on 7 October 2021. [2] This passage through the planetary region of the Solar System will reduce the orbital period from millions of years to thousands of years. [1]
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]
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 ...
