Comet C/2012 SI (ISON), Close Approach 26 Dec 2013 I made this video more than a year ago, a week after it was discoverd on 21 Sep 2012, now that the comet approaching nothing much changed since then! Comet C/2012 S1 (ISON), was discovered on 21 Sep 2012 its formal name, was found by Russian amateurs Vitali Nevski and Artyom Novichonok of the International Scientific Optical Network (ISON). From late October through late-November, Comet ISON, brightening sharply from 7th to 1st magnitude in the eastern sky at dawn. When closest to the sun at Perihelion on Nov. 28 its predicted to shine a spectacular -7 magnitude or almost 10 times brighter than Venus. A second round of excellent visibility commences immediately after perihelion as Comet ISON comes behind the sun and banks north into Ophiuchus and Hercules in early December. While the comet fades during this time, its likely to have a spectacular tail and be as bright as magnitude -4. Both hemispheres will get great views, with the northern favored as Christmas approaches. Indeed, northerners will see it at both dusk and dawn. The comet will pass nearest Earth at a distance of about 64 million Km, in Dec 2013, close to Northern Constellation of Draco. The comet will come to perihelion (closest approach to the Sun) on 28 November 2013 at a distance of 0.012 AU (1,8 million km; 1,1 million mi) from the center point of the Sun. Accounting for the solar radius of 6.955×105 km, the comet will pass approximately 1,100,000 kilometres (680,000 mi) above the Suns surface. Its orbit is nearly parabolic, which suggests that it may be a new comet coming fresh from the Oort cloud. It will pass about 0.43 AU (64 million km; 40 million mi) from Earth on 26 December 2013. Comet ISON forecast to shine as brightly as Vega next March. Its important to remember that comets dont always perform as expected. Any prediction of a comets brightness is subject to change, sometimes radically Will C/2012 S1 (ISON) become a Great Comet, too? very soon we find out ! Music: Deep by Ryan Farish
