What constellation is Draco?

Draco is a constellation that can be seen all year round in the northern night sky. In the north of Beimian, it really looks like a dragon winding between the Ursa Major, the Xiao Xiong Major and the Ursa Major, spanning the vast sky. Gaolongtou is close to Wuxian County and consists of four stars, forming a quadrilateral. The long dragon body encircles the North Star for half a circle. The faucet consists of four stars: 2, 3, 4 and 5. A straight line leads from the two stars in the faucet bucket to the north, and you can find the North Star. It is an arched constellation, which can be seen all year round in the northern hemisphere. On May 24th every year, the center of Draco crosses the sky. Tianlong constellation is the eighth largest constellation in the whole day.

Tianlong constellation

The dragon star (called "right pivot" in Chinese) of the dragon tail is a fourth-class star. Although it is not bright, it is a famous star in ancient Egypt because it was the "North Star" 4,000 years ago. Legend has it that there is a hundred-meter-long tunnel under the pyramid of King Chiapas left over from ancient Egypt, in the opposite direction to the dragon star Alpha.

The ancient Egyptian gods looked out from the tunnel at the "North Star" at that time. The head of the dragon is in the north of Wuxian, and the dragon body surrounds the North Star for half a circle. The beta star in Tianlong (named "Tianjing III" in Chinese) is a G2 Ⅱ yellow giant with a time of 2.79 and a distance of 365,438+00 light years. The gamma star in Tianlong constellation (named "Tianjing IV" in Chinese and Eltanin in western, translated as the leading star) is the brightest star in the constellation, and it is a K5 Ⅲ superstar, with a distance of 1 10 light years. NGC5866 is a famous E6p elliptical galaxy with an apparent magnitude of 10.0.

Purple Mountain Observatory of Chinese Academy of Sciences announced the astronomical phenomena in June 20 12. On June 20 10, the public will have three chances to see meteor showers, namely, the Draco meteor shower on June 8/kloc-0, the Southern Taurus meteor shower on June 26/kloc-0, and the 260-degree meteor shower. According to the Purple Mountain Observatory, the Draco meteor shower is the most anticipated one in June of 5438+00. The meteor shower in southern Taurus is a gift from comet 2P/ Enke to our planet. The flow of meteor shower in southern Taurus is not large. On the night of 10, when the forecast is extremely high, only a few meteors in the group can be seen in one hour, of course, under the lucky circumstances. It is reported that most meteors in the southern Taurus meteor shower seem to be slower and have more bright meteors. Many experts from the International Meteor Organization believe that this year's Draco meteor shower is likely to break out. From June 6th, 10 to June 6th, 10, its radiation point was near the quadrangle at the head of Yu Tianlong Star. For the area north of 35 north latitude, the radiation point is in the arch pole area and will never fall. According to the current forecast, this year's Draco meteor shower will occur at 19: 00 Beijing time, and the observation conditions in eastern China, the Russian Far East and Japan are very good. Halley's comet 1P brought us the Orion meteor shower, and its active time was from 65438+10.2 to165438+10.7. The peak flow of Orion meteor shower in 20 12 years may appear around 10 and 2 1, and the estimated flow is about 20 per hour. It should be noted that the radiation point will not rise until after 22: 00, and the horizon is higher in the middle of the night, so the observation conditions are very good.
