Comet ISON, formally known as C/2012 S1, was a sungrazing comet from the Oort cloud which was discovered on 21 September 2012 by Vitaly Nevsky (Віталь Неўскі, Vitebsk, Belarus) and Artyom Novichonok (Артём Новичонок, Kondopoga, Russia).
ISON is managed by the Keldysh Institute of Applied Mathematics, part of the Russian Academy of Sciences. [2] [3] It was credited for the discovery of comets C/2010 X1 (Elenin), [4] P/2015 PD 229, [5] and C/2012 S1 (ISON), [6] the latter popularly known as Comet ISON. The minor planet 365756 ISON is named for the network. [7]
P/2015 PD 229 (Cameron–ISON) is a periodic comet that was initially thought to be an active centaur upon discovery. It orbits the Sun between Jupiter and Saturn once every 19.2 years, and has appeared to have made several close encounters with the giant planets from 1889 to 1949. [4]
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 ...
By definition, a hyperbolic orbit means that the comet will only travel through the Solar System once, with the Sun acting as a gravitational slingshot, sending the comet hurtling out of the Solar System entirely unless its eccentricity is otherwise changed. Comets orbiting in this way still originate from the Solar System, however.
C/2020 F3 (NEOWISE) or Comet NEOWISE is a long period comet with a near-parabolic orbit discovered on March 27, 2020, ... (ISON). From the infrared signature, ...
"Periodic comet" is also sometimes used to mean any comet with a periodic orbit, even if greater than 200 years. Periodic comets receive a permanent number prefix usually after the second perihelion passage, which is why there are a number of unnumbered periodic comets, such as P/2005 T5 (Broughton) [ it ] .
