Comet ISON to make Dangerous Closest Approach to the Sun

Comet ISON to make Dangerous Closest Approach to the Sun

Comet ISON is known to go out of our solar system's distant shell around 10,000 years ago. The region is called as the Oort cloud and started to go close to the sun.

Discovery of comet ISON in last September was a result of a research by two Russian amateur astronomers. Since then, it has been recognized as a possible comet of the century. However, it has to cope with dangerous perihelion or closest approach to the sun in November.

ISON is a sun grazing comet that has an orbit to bring it within 850,000 miles of the sun. According to scientists, the closet approach of ISON will be about 730,000 miles above the surface of earth's star.

This boundary lies some 230 million to 280 million miles from the sun. The radiation of earth's star will begin to have the effect on the comet and will make it appear brighter by driving off more of its water.

It will fly by mars in October and then Mercury in mid-November. More material will be boiled off ISON by intense solar radiation. The comet could be broken into pieces because of pressure from solar particles. Besides, there will be a great gravitational stress created by tidal forces and the comet's tail could be ripped right off by one ill-timed solar storm.
