ISON (C/2012 S1) comet is approaching the Earth. The brightness of the comet can soon achieve the brightness of the full moon. When flying past our planet, the celestial body will leave a large number of particles. It will be possible to observe particles in almost every corner of the world.
ISON comet will near Earth in December 2013, when scientists can obtain new data on the nature of comets. The comet was discovered in September 2012 by astronomers Artyom Novichonok and Vitaly Nevsky of the observatory in Kislovodsk.
C/2012 S1 will come to perihelion (closest approach to the Sun) on 28 November 2013 at a distance of 0.012 AU (1,800,000 km; 1,100,000 mi) from the center point of the Sun. Accounting for the solar radius of 695,500 km (432,200 mi), C/2012 S1 will pass approximately 1,100,000 km (680,000 mi) above the Sun's surface. Its trajectory is nearly parabolic, which suggests that it may be a dynamically new comet coming freshly from the Oort cloud. On its closest approach, C/2012 S1 will pass about 0.0724 AU (10,830,000 km; 6,730,000 mi) from Mars on 1 October 2013, and it will pass about 0.429 AU (64,200,000 km; 39,900,000 mi) from Earth on 26 December 2013
