The rare planetarium Why gathered in 2012? Experts said the Department of movement cycle coincidence

In the early morning of May 21, Sky staged a "Circle eclipse rare astronomical phenomena, and a yellow with red and golden hook," gradually rising in the eastern sky;
June 6, the transit of Venus will also Jingxian Sky, would like to see her again, that 100 years after;
In August, the Perseid meteor shower is great when the flow of about 100 per hour across the sky;
September, December, Uranus and Jupiter stage by turns "red".
Why 2012 will be so many rare astronomical phenomena?
Eclipses, the most spectacular planetarium?
In the early morning of May 21, fantastic annular eclipse appeared in Sky, which is in our country within five years of the 4th great eclipse.
Su Yi, director of the Chinese Astronomical Society, professor of Nankai University, the solar eclipse in a straight line between the moon run to the Sun and the Earth occurs when the, then, for some areas on Earth, the Moon is located in the sun in front of, from some or all of the light of the sun is blocked, it looks as if part or all of the sun disappeared. Eclipse Sub-total solar eclipse, annular eclipse and partial eclipse three.
The transit of Venus, the most rare celestial phenomena?
2012 of the most anticipated Sky "transit of Venus" splendid performance will be June 6. Astronomy experts suggest that, until 2117 could see the last to want to see that on more than 100 years, the transit time of up to six hours, most parts of China is the best observation areas.
Astronomy education experts, Tianjin Astronomical Association, Zhao Heng said the inside of the orbit of Venus in Earth orbit, and some special moments, Earth, Venus, the sun in a straight line, then on Earth can see that Venus is like a small black spots, like slow-moving surface of the sun, astronomy called "transit of Venus".
Meteor shower, the most romantic Sky?
May, Sky brilliant sky staged May 5, the Aquarius meteor shower. Researcher at the Purple Mountain Observatory, Chinese Academy of Sciences, the king thought, this is the first half of this year, meteor rain, the larger flow of time, and this year a total of seven large-scale meteor shower.
Aquarius meteor shower after this August in order to usher in the Perseid meteor shower. In addition, Orion meteor shower will occur on October 18 -23, the Leonid meteor shower will occur after November 18. The year's most anticipated Gemini meteor shower will be staged at the end of the year, continued from December 7 to 17. In the early morning of December 14, Meteor will likely outbreaks, and the day two days of the Lunar New Year, all night with no moonlight interference, best observing conditions.
Planet red day, the most exciting astronomical phenomena?
Planets washed annually Sky one of the main, it is also for the public to bring the favorable opportunity to appreciate the planet. Astronomy experts said this year, Mars, Saturn, Neptune, Uranus and Jupiter turns to put on "red" drama.
The king thought, the so-called red planet day the planets and the sun just points at the Earth on both sides, the three almost in a straight line, then the planet Earth from the nearest, the highest brightness, is the best time of observation.
Mysterious Neptune at Opposition on June 29, 2012. September 29, 2012 Uranus opposing the public with the naked eye can be reflected in its hosting the Games. 2012 staged Opposition good show of the planets in the solar system "burly" planets - Jupiter, it will be December 3 at Opposition. Then, amateur astronomers by the naked eye can clearly in the night sky to see Jupiter in Taurus.
Several different planetarium gathered in 2012,
Its movement cycle coincidence
2012, not only Sky staged one after another planetarium good show this year, the calendar and lunar calendar with leap year and the year two spring astronomical phenomena.
The astronomer explained astronomical phenomena is the objective law. For example, the food of the sun and moon is the sun, the moon, the earth of these three objects, very regular movement revolution, by the relative position change between them, under certain conditions the formation of both the common and ordinary. Modern astronomy can accurately calculate the time before and after thousands of years of eclipse, and global throughout the visible location; transit of Venus twice a transit group, an interval of eight years, but the interval between the two groups. There are more than 100 years. The solar activity has an average of 11 years of change cycle is about to enter the 24 activity cycle peak year. A solar activity peak occurred after the year 2002. Calendar leap year is roughly once every four years, which means that for every four years in February in a leap year 29 days. Lunar 19 years, seven years is a leap year, to set an intercalary month in leap year, an increase of a lunar month. While the Gregorian calendar and lunar calendar is a leap year and the year two spring astronomical phenomenon, an average of more than ten years, the last in 2001.
Astronomy experts say that the 2012 rare astronomical phenomena, concentrated in a year and is rare. However, by the above analysis shows that several phenomena are several different planetarium movement cycle happens to coincide in 2012 due to purely coincidental.
