Comet Encke and Comet ISON
Comet Encke and Comet ISON are converging for a photogenic close encounter.


but as seen from the STEREO-A spacecraft, they are going to get very close!" he says. "We are probably a couple of days away from seeing two comets almost side-by-side in that camera, with long tails flowing behind them in the solar wind. To say that such an image will be unprecedented is rather an understatement

Re: Comet Encke and Comet ISON
a few facts about comet Encke



Comet Encke or Encke's Comet is a periodic comet that completes an orbit of the Sun once every three years — the shortest period of any known comet.
It was first recorded by Pierre Méchain in 1786, but it was not recognized as a periodic comet until 1819 when its orbit was computed by Johann Franz Encke; like Halley's Comet, it is unusual in being named after the calculator of its orbit rather than its discoverer. Like most other comets, it has a very low albedo, reflecting only 4.6% of the light it receives. The diameter of the nucleus of Encke's Comet is 4.8 km.[2]

During the November 2013 perihelion passage the comet is expected to brighten to apparent magnitude 7.[4]


comet Encke was discovered in 1786 but Ison was only found in the last couple of years...crazy!

I just thought of the sign of the son of man in the heavens and that the largest orbiting comet (Ison) and shortest orbiting comet(Encke) will be side by side.. the first and the last.. Weird timing huh?

Re: Comet Encke and Comet ISON
The Taurids and Beta Taurids, which are a meteor showers occurring in November and June, are believed to be the dust trail left by Comet Encke.



Encke is so much smaller than Ison but still effects earth

the show of the heavens now look at the signs


comet Encke and Tunguska


On June 17th, 1908, around 9 a.m. a comet or asteroid exploded in the air above an uninhabited area of Siberia near the Tunguska River. L.
Kresak in the Journal Astronomical Institutes of Czechoslovakia Bulletin, vol. 29, no. 3, 1978 proposed that debris from Comet Encke was responsible for the 1908 explosion in Earth atmosphere.


The blast in 1908 leveled an estimated 80 million trees covering 830 square miles (2,150 square km). Its explosive energy was estimated at fifteen megatons. For comparison, the bomb dropped on Nagasaki near the end of World War II was .023 megatons—652 times less powerful than the object that exploded over the Tunguska River in 1908. The last nuclear bomb to be used in warfare simply took more lives since it was dropped intentionally on a heavily populated area. Imagine if Earth had spun a couple more hours on its axis and the airburst happened not over an unpopulated area in Siberia but over London. The city and surrounding area would have been leveled, killing millions.
