According to a report from the Huffington Post on Dec 31, 2012, Comet ISON was discovered by two amateurs; one from Belarus and one from Russia in September.
ISON is spectacular and has light even brighter than the full Moon. The comet was first seen when it was at a distance of 600 million miles (965 million km) from the sun beyond planet Jupiter’s orbit.
According to the research ISON may appear a large as it was spotted at such a great distance. If the comet survives, it is expected to light up the night sky in the Northern Hemisphere in December 2013.
Comet experts say that the ISON’s path is almost to that of Kirch’s Comet spotted in the year 1960. Also known as the Newton’s Comet, it was vivid enough to be seen in daylight and had a long tail.
ISON may become one of the greatest comets in the history. According to researchers by the month of August it will be at a distance of more than 200 million miles (320 million km) from the Sun. It would show its halo by that time.
