There will be a total eclipse of the sun on  July 22

A total solar eclipse is a spectacular natural phenomenon and many people travel to remote locations to observe one. The 1999 total eclipse in Europe helped to increase public awareness of the phenomenon, as illustrated by the number of journeys made specifically to witness the 2005 annular eclipse and the 2006 total eclipse. The next solar eclipse will occur on August 1, 2008, and will be a total eclipse.

The so-called "food" is a celestial body that was another celestial body or its Heiying Yanzhe all or part of the astronomical scene. Ri Quansi main solar eclipse, the partial eclipse and three on the Environment and Food. The principle is the solar eclipse occurred on Earth, some areas were covered by the shadow caused. Shuori solar eclipse will occur in that first day of the Lunar New Year (New Moon). This is because only in that day, the moon will appear in the Sun and the connection between the Earth, so will it be possible to block the sun and the moon formed the solar eclipse. Similarly, the eclipse will appear in Wangri that the Lunar New Year 15.

You might ask, why is not the first day of each month will be a solar eclipse, why not the 15th of each month will be a penumbral eclipse » This is because in addition to the above conditions, the impact of the solar eclipse and the eclipse there are other factors. We the Earth around the sun to the track known as the ecliptic, the moon around the Earth to the track known as the White Road. Ecliptic plane and white plane, not the same, among them an average of 5 ° 09 'angle, and always changing. Only when the moon to run, and yellow or white Road intersection near the intersection and down only when a solar eclipse.

The type of solar eclipse

A total solar eclipse of three, namely: the partial eclipse, on the Environment and Food and Riquan Shi. The moon covered the sun is part of the partial eclipse. Moon only cover the central part of the sun, the sun also exposed a circle around the face, seems like a halo called on the Environment and Food. The sun is completely covered Riquan Shi. This three different solar eclipse occurred with the sun, moon and Earth all three of the mutual changes of position, and also decided on the Moon and the distance between the Earth changes.
The moon was much smaller than the sun, it is about the diameter of the sun's diameter 1/400, and the distance between the Earth and the Moon also is almost the distance between the Sun and the Earth's 1/400, from the earth, the moon and Sun's round face almost the same size, which can cover and a solar eclipse.
Earth to the Moon and are elliptical orbit to the public, whether the distance between the Sun and Earth, or the distance between the Earth and the moon, is not fixed, and sometimes distant, sometimes relatively recent and therefore the length of the moon Benying not the same , The longest time the moon Benying 379,660 km, 367,000 km for the shortest possible time, the Earth and the moon and the distance between the last at 356,700 km, the farthest reaches up to 406,700 km. If a moment of Earth and the Moon Benying than the distance between the moon, the moon on Earth was Benying sweep of the area will be able to see Riquan Shi. If the moon Benying Earth and the moon than the distance between the small, cutting-edge to the moon Benying not the earth's surface, then in the video pointed out the extension of small shadow cone (called pseudo-Benying) sweep of the area can be seen on the Environment and Food . The sweep was the moon penumbral zone can see the partial eclipse, the partial eclipse in the region-wide water from the area near, the greater the extent of the partial eclipse. Penumbral lunar Benying and did not sweep the place, simply can not see the solar eclipse.
Following is the century (1901-1999) in the world within the framework of the number of solar eclipse:

The number of species
78, the partial eclipse
On the Environment and Food 73
Riquan Si 71
Mixed Fresh 6
Total 228

The process of solar eclipse
The process of the solar eclipse can be divided into five phases, but only to have the entire process of Riquan Shi, and the partial eclipse on the Environment and Food is not potable both light and Health. Early losses: the sun and the moon, the first cut, just west of the sun-Cut east of the moon moment. Fresh both: the sun and the moon within the first cut, sun-moon has just been totally masking the moment. Very fresh: the sun and the moon Centre Centre at the smallest distance. - Health: the sun and the moon, the second cut, sun-exposed just west of the moon moment. - Round: the sun and the moon, the second cut, sun-moon has just completely left behind the moment. Early losses, both fresh, light and health-circular also called the first, second, third, fourth contact.
