Comet ISON: A Sungrazing Comet

Comet ISON (or C/2012 S1) is a sungrazing comet which was discovered in September 2012. A sungrazing comet is a comet which passes extremely close to the Sun. Comet ISON will come as close as 730,000 miles to the Sun on November 28, 2013. If it does come out without breaking up after it passes the Sun, the comet would be visible in the Northern Hemisphere with the naked eye (as it would be incredibly bright). It's Comet ISON's first trip around the Sun coming directly from Oort cloud. The comet's closest approach to Earth will be on December 26, 2013 (assuming that it survives the closest approach to the Sun) when it will be 40 million miles away.
