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] and C/2012 S1 (ISON), [5] the latter popularly known as Comet ISON. The minor planet 365756 ISON is named for the network.

Comet ISON [20] taken with the Wide Field Camera 3 on April 30, 2013. [21] About 83% of the sungrazers observed with SOHO are members of the Kreutz group. [22] The other 17% contains some sporadic sungrazers, but three other related groups of comets have been identified among them: the Kracht, Marsden and Meyer groups.
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 ...
A fact from Comet ISON appeared on Wikipedia's Main Page in the Did you know column on 2 October 2012 (check views).The text of the entry was as follows: Did you know... that when the newly discovered comet C/2012 S1 reaches its perihelion on 28 November 2013, it may appear brighter than the full moon?
There are some bona fide behemoths sailing around the solar system.In 2021, astronomers identified a gargantuan comet — an ancient mass of ices, dust, and rocks — hurtling through our cosmic ...
Comet Tsuchinshan-ATLAS has an 80,000 year orbit and, it just so happens, that it is now approaching its closest pass to Earth. On Wednesday, the comet made its closest approach to our sun and on ...
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.
