We have some spectacular company coming next year...not one, but TWO major comet events are expecting to fill our skies in 2013.

These are described as "Great Comets", much brighter not so much because of their size, but much CLOSER than any most folks alive today have witnessed in their lifetimes.

As the Article summarizes:

"Although comets are not uncommon in our solar system, Great Comets only appear once a decade on average .

There’s is no major significance about the size of “Great Comets“, rather they are simply defined as comets that become exceptionally bright and can be seen by casual observers with the naked eye.

This usually has to do with their distance from Earth.

So what are we to make of the possibility of two Great Comets flying by Earth in 2013?

Astronomers have discovered two new comets that are fast approaching our planet and have the potential to be Great Comets.

One might be “bright enough to be seen in the day” and the other is projected to become “one of the brightest in history” and possibly “outshine the Moon“.

The first comet, named C/2011 L4 (PANSTARRS), is expected to make its arrival in March 2013.

According to astronomers, it will be “potentially visible to the naked eye low in the western horizon just after sunset” and also has the “potential that it may be visible during the day.”

Richard Wainscoat, an astronomer at the University of Hawaii who co-discovered the comet, claims there is no danger of collision with Earth but admits “since we don’t have a lot of data on it, we really don’t know the orbit well enough right now.”

The second comet, the one which could possibly outshine the Moon, was only just discovered this September and is called 2012 S1 (ISON).

Astronomers predict “current orbital predictions indicate the comet will look brightest to us in the weeks just after its closest approach to the sun, on November 28, 2013.”
