ISON comet reappeared and approached .

ISON will be the brightest in the sky from 21 to 28 November and the week after that, if you survive the approaching 0,012 astronomical units from the Sun ( an astronomical unit is equal to the distance between the Earth and the Sun , or about 150 million km) .
" In January 2014 ISON ( if you survive ) will pass the Earth and can be sprinkled powerful flow of space dust ," says a report of the conference Gindilis Cherbakul in town . "
" Particles of comet dust will reach the Earth's surface in a few months , the youngest - a few years after the passage of the comet by the Earth . They can be collected over the entire surface of the planet. And you can choose the most appropriate locations distant from the sources of technogenic dust ( alpine glaciers and snow , arctic regions , Antarctica ) , and areas with high magnetic anomaly , "says Gindilis quoted by RIA Novosti.
Comet ISON was opened on 21 September 2012 by Russian astronomers Antyom Novichonok and Vitaly Nevsky 40 -inch telescope.
 It comes from the Oort cloud , a billion miles from the Sun. The path of the comet will take her close - 1.2 million kilometers above the visible surface of the Sun on 28 November .
It is not clear whether it will survive the meeting.
For some time the comet was not visible because it was hidden from the sun , but in August again saw her astronomer Bruce Gary.
The European Space Agency is preparing to observe the comet ISON, which in November is expected to be seen with the naked eye in the sky at night.
Thin atmosphere around the nucleus becomes more visible because ice surface is heated by the sun and becomes a gas.
Dusty debris from the air passing in a queue , which will also become more closer to her
" Mars Express" ESA has started observations and analyze the body composition of the comet over the next two weeks. ISON will be closest to Mars on October 1 - a distance of 10.5 million kilometers , six times closer than it would reach Earth.
In November and December apparatus ESA's " Venus Express" and "Test 2" will continue to monitor the comet.
