ISON is an average sized comet at about 2 miles wide. Some can be over 30 miles wide, but ISON may be one of the brighest, and brighter than the moon (but won't emit as much light because it's smaller than the moon) because it will get much closer to the sun (750,000 miles). Its tail could be about 70 degrees long which is seen as seven fists wide at arm's length. That would rival the Great Comet of 1680, if it doesn't burn out.
