Lyra lyra North one-day constellation. Center: 18:50 ascension, declination 36 °. Area of about 286 square degrees. In Draco, between Hercules and Cygnus. Block the visual magnitude brighter than 6 are 53 such stars, including stars brighter than 4, etc. are eight. Summer, the West Bank in the Galaxy a very bright stars, some of it around the small stars form the constellation Lyra. Vega's magnitude is 0.05m, is the fifth day bright stars. It is 26 light years away from us, is the first accurate determination of astronomers from a star. Remember we said that, due to precession, the North Star always turns on duty. In another 12,000 years, Vega will become the North Star was the. At that time, more important than it is now definitely Lyra. Lyra's brightest star for the day piano a star - "Weaver one", that is, we often say, "Vega", the English called vega, derived from the Arabic "swooping vulture (swooping vulture)". The brightness of 0.03, was blue and white, 25 light years from Earth, is the fifth day bright stars in the Northern Hemisphere is second only to Bootes the "horn" star, 25 times the brightness of the sun. Vega around in some dark stars, the more obvious is the second south-east of the following four stars by the small diamond-shaped form, according to legend was used by Weaver weaving shuttle, including the southwest corner of the day piano b Star " gradually Taiwan II "(English name sheliak) is a double star, and its primary star is an eclipsing star, the brightness range of 3.3 to 4.4 between cycle 12 and 22 hours. He is almost through with the two stars, the gas emitted each rotation, the two stars to each other due to gravity and squash, and place a continuous variable light, food and food before the end of the time is not clear yet in the universe There are other such similar variable stars, known as "Lyra b-type variable optical star." Observation, you can Tian Qin g (brightness 3.24), and Tian Qin k (brightness 4.33) to compare, a small telescope can see the distance of its companion star, etc. 7.2. The same as Leo, Lyra and there was a very well-known meteor shower. It appeared in the annual April 19 to 23, particularly among the 22 most spectacular. On its first world record in the classics of ancient China, "Spring", the it vividly recorded in 687 BC, a meteor shower in Lyra the outbreak: "of the night, stars fell like rain." In late April, four in the morning Lyra , when the five-point rise to the zenith, in order to more clearly see the meteor shower, and get up early.

It's first star appears in the photo. β (gradually _set_s II): 3.45 and so on, spectral type B8 II, Fengyun fresh variable names to be used as a kind of variable star called - gradually table II variable stars. γ (gradually and Taiwan): This multi-satellite system's main star magnitude 3.24, spectral type B9 III. δ: the other a six-brightness blue and white stars and a half wandering the rules in 4,5, etc. composed of red giant binary star system. ε: well-known quadruple star, also known as "both star" because it is composed of two pairs of binary stars. ζ: also can use binoculars to distinguish the binary. RR Lyrae stars: RR Lyrae type variable stars are named according to it. Vega in Lyra and Altair Aquila, Cygnus Tianjin four-star, arranged in the summer sky right angle triangle, as the Summer Triangle (I called the summer triangle, Summer Triangle). Vertices at right angles to the Vega, in the longer side of the triangle is Altair, and the other was a four-star Tianjin.

Xinhua Nanjing, April 22 (Xinhua CAI Yu Gao, Zhou Runjian) Jiangsu, Tianjin two Astronomical Society Bulletin, at 6:30 on the 23rd Lyra meteor shower will reach its apogee. In the previous few hours, there will be dozens of meteors per hour across the sky. Milky Way in the beautiful West Coast, has a well-known bright star Vega, which, around some of the small stars form the constellation Lyra. 4 months late each year, this constellation in the sky meteor shower will be on stage.

The orbit of comet 1861 I formed the Lyra debris meteor showers, the meteor shower as a whole is one of three periodic meteor shower in astronomy also plays an extremely important position. Deputy Secretary-General, Jiangsu Province, Yan Jiarong Astronomical Society, this year's Lyra meteor shower will be at 6:30 on the 23rd to reach its apogee. Then, if the weather is good, Amateur astronomers in the 22 midnight to 23 observations to the east before dawn. Purple Mountain Observatory, Chinese Academy of Sciences researcher also reminded the king thought, meteor showers because of human current forecast also like solar and lunar eclipses as accurate, so the public observation must be psychologically prepared before, when there may not be observed meteor. Scientists pointed out that April 22, 2008 happened to be nearly full moon, so we can only see the faint meteors, seen above, a scientist describes the case of meteor showers occur. Scientists believe that Lyra two thousand six hundred years before the meteor has appeared in Chinese history also records that Lyra meteor shower occurs in BC six hundred and eighty seven. Lyra fast meteors, meteor one hundred and nine thousand miles per hour speed of the collision the Earth's atmosphere, to send a very bright light.
