Transcript of Comit Ison
The Path Of Comet Ison
Shortly after its discovery, similarities between the orbital elements of C/2012 S1 and the Great Comet of 1680 led to speculation that there might be a connection between them. Further observations of ISON, however, showed that the two comets are not related.
Earth will pass near the orbit of C/2012 S1 on 14–15 January 2014, well after C/2012 S1 has passed, at which time micron-sized dust particles blown by the Sun's radiation may cause a meteor shower or noctilucent clouds, however, both events are unlikely. Because Earth only passes near C/2012 S1's orbit, not through the tail, the chances that a meteor shower will occur are slim. In addition, meteor showers from long period comets that make just one pass into the inner solar system are very rare, if ever recorded. The possibility that small particles left behind on the orbital path—almost one hundred days after the nucleus has passed—could form noctilucent clouds also is slim. No such events are known to have taken place in the past under similar circumstances.[
About Comet Ison
For months, all eyes in the sky have pointed at the comet that is zooming toward a blisteringly close encounter with the sun.
The moment of truth comes Thursday — Thanksgiving Day.
The sun-grazing Comet ISON is thought to be straight from the Oort cloud. The closer the comet gets to the sun, the faster it gets. Last Thursday, it was clocked at 150,000 mph. Thought to be less than a mile wide, ISON will either fry and shatter, victim of the sun's incredible power, or endure and quite possibly put on one fabulous celestial show.
Should it survive, ISON, pronounced EYE'-sahn, would be visible with the naked eye through December, at least from the Northern Hemisphere.

ISON IS Moving Toward The Sun
It’s the comet of the century! It’s a dud! It’s… maybe somewhere in between. Those have been the reactions in recent weeks to the approach of Comet ISON to the inner solar system. Since its discovery last September by the telescopes of the International Scientific Optional Network (ISON), the comet—officially designated C/2012 S1—has attracted interest from astronomers who predict that its close passage to the Sun could make it not only visible to the naked eye, but potentially a brilliant object rivaling the brightest stars (although not, unlike some reports in the media claim, to be as bright as the full Moon.) Others, though, are more skeptical, with some suggesting the comet is not brightening as fast as expected.
