Extremely special comets will appear in 2013

Astronomers believe that ISON, comet will appear on November 28, 2013, the brightest ever.

Comet ISON was found 14 months before it was in the Sun's closest position. In addition, this star is located quite favorable to observe when it is closest to the Sun on the morning of November 28 and the next day.

The ISON star was discovered by Russian scientists Vitali Nevski and Artyom Novichonok on September 21, 2012 using a 0.4km-diameter reflective telescope belonging to the International Scientific Observation System located in Kislovodsk, located at the northern foot of the Caucasus mountain, Russia.

When discovered, this star is still quite faint and 1 billion km from Earth, belonging to the Cancer constellation. At that time, the star had only 18.8 brightness in the stars' brightness measure. This means that the ISON comet is dimmer than the faintest stars visible to the naked eye of 100,000 times.

Currently, ISON is going through the Gemini star and will fly south 1 degree above the star Castor. However, the star is still quite fuzzy and is about 762 million kilometers from the Sun, located in Jupiter's orbit.

According to data obtained from the observations, ISON comet will fly over the Sun on November 28, 2013 and then it flies at 684km / h. This star will be 1.18 million kilometers away from the solar light, grazing the surface of the Sun.

ISON Comet - this may be the brightest star ever, surpassed
through both the 1997 Hale-Bopp comet and the Mc Naught comet in 2007.

In the 2013 astronomical calendar, astronomer Guy Ottewell writes: 'If using our current measurement system, ISON comet has a brightness of -12.6; equal to the brightness of the Moon when it is the most rounded ".

If this statement is correct, we will have the opportunity to admire this star during the day, which happened in the 17th century.

What makes the comet ISON so much concerned?

The reason is that the ISON comet has an orbital quite similar to the orbit of the Great Comet, discovered in 1680.

It is this question that raises the question of whether these two stars are 1, or at least do they have any connection?

The comet was discovered by telescope astronomer Gottfried Kirsch, the first star to be discovered by this method. On December 18, the star is located closest to the Sun, 502,000km from the Sun's surface.

This star can be seen during the day when flying over the Sun. It reappeared in the evening at the end of December and died at the beginning of January 1681.

However, some comets are unpredictable people , and they often rarely follow what we anticipate.
