ISON’s average speed throughout September will be 67,957mph. It will continue to accelerate steadily until 28th November when it’ll whip around our Sun at an astonishing 425,000mph!
Comet ISON is roughly heading towards the centre of our Solar System. It will pass within 1.2 million miles of the Sun’s surface on 28th November when it reaches perihelion (the point when its at its closest to the Sun) before being whipped around to head back ‘roughly’ in the direction it came.
As ISON makes its outbound journey, it will pass over the northern hemisphere of Earth at a distance of around 40,000,000 miles on 26th December.

If ISON lives up to the hype, you could expect to see the Comet with the unaided eye anywhere between the middle of November until the middle of January 2014 (depending where you are on the planet).
Over the past 10 days, between August 20th and August 30th, Comet ISON traveled a distance of approximately 0.161 AU.
0.161 AU = 14,965,885 miles
0.161 AU = 24,085,257.2 kilometers
That’s an average speed of roughly 1.49 million miles per day, or 2.40 million kilometers per day.
Comet ISON’s coma, which is a cloud of gas, was approximately 3,100 miles across,
or 1.2 times the width of Australia, based on observations from NASA’s Hubble Space Telescope on April 10, 2013.
Since Comet ISON is a comet and not a planet or a moon, it has a dust tail.
On January 30, 2013, NASA’s Swift Telescope observed that Comet ISON’s dust tail extended more than 57,000 miles.
A few months later on June 13, 2013, NASA’s Spitzer Space Telescope observed that Comet ISON’s dust trail extended more than 186,400 miles (300,000 kilometers) long.
As a comparison, Comet Halley’s tail was approximately 13.67 million miles (22 million km) on February 22, 1986, thirteen days after it reached perihelion on February 9, 1986.

End of the World 2013? Comet ISON Growing Brighter; Social Media Networks to See Fresh Round of Doomsday Talks
Monday, June 10, 2013 10:48
(Before It's News)
Comet C/2012 S1 (ISON) appears ready for a big cosmic show by Q4 2013. Gemini Observatory has photographed Comet ISON looking stronger and brighter, as if teasing Earth dwellers as it approaches the Sun.
Meanwhile, expect social media networks to be flooded by another round of doomsday talks as ISON makes its historic solar encounter.

Will Comet ISON 2013 give a spectacular show in the sky?
ISON, which is expected to come to its closest approach to the Sun in November or December 2013, could amaze or disappoint observers, too. Scientists couldn’t estimate how bright it would be until a couple more months.
But it is a very promising celestial piece.
Comet ISON “could still become spectacularly bright as it gets very close to the Sun,” said astronomer Karen Meech, of the University of Hawaii’s Institute for Astronomy.
She pointed out, however, “I’d be remiss if I didn’t add that it’s still too early to predict what’s going to happen with ISON since comets are notoriously unpredictable.”
Why is Comet ISON linked to doomsday, End of the World 2013 prophecy talks?
Nostradamus reportedly made a prediction that “the pope to replace Benedict XVI will ‘flee Rome’ in the month of December, at a time when the sky has two suns.”
This is connected to earlier rumour-based speculations that Pope Francis, the 266th and current pope of the Catholic Church, will be the last pope to be named.
As it is not clear whether ISON would be bright enough in December, a ‘sky with two suns’ remains part of popular myth - a topic popular across social media channels.
