Parade of planets
libre 14
A parade of planets has produced a real debate over whether or not the world will end.
An astronomical phenomenon
This is an astronomical phenomenon during which several planets line up. This process can cause the sun or moon to darken, for example. 
A minor parade is when 4 planets line up (Mars, Saturn, Mercury, Venus). It can be observed once a year.
The Grand Parade, of course, is formed from a line of most of the planets in the solar system. In this case, there are 6 of them: Earth, Venus, Mars, Jupiter, Uranus, Saturn. It occurs much less frequently than the minor parade of planets - only once every 20 years.

Why the parade of planets, which occurred on December 21.12.2012 caused such a stir? The fact that in this parade will take part planets from other systems. About it have already written and representatives of the Maya tribes and modern astrologers.
There are many opinions about it. It is interesting the attitude of people to this process. Some believed that the end of the world will come. But still most of these expectations were not justified, the end of the world did not come. And yet, we would like to believe that these processes can affect the improvement of life on our planet.
