ison_10082013-sm.jpg Comet ISON (C/2012 S1)
Discovered by: Vitali Nevski and Artyom Novichonok at the International Scientific Optical Network (ISON) near Kislovodsk, Russia.
Discovery date: September 21, 2012
Type: Sungrazing comet
Perihelion: November 28, 2013 (0.0124 AU or 1,860,000 km; 1,150,000 mi)
Here's what we know about this Oort Cloud comet:
--It is set to be the most observed comet by NASA ever - 16 space-based assets, including astronauts aboard the International Space Station.
--ISON is a pristine comet from the Oort Cloud - this is its first time visiting our solar system.
--The comet is a sungrazer. It will fly through the atmosphere of the sun, and may not survive closest approach on 28 Nov 2013.
--Another comet from the Oort Cloud will be visiting next year, so scientists will be comparing both to see how comets from this icy reservoir of debris beyond our solar system differ from other comets.
