Which constellation does Vega belong to?

0 1 belongs to Lyra?

Vega, also known as Vega or Lyra? (? Lyrae, the brightest star in Lyra, is about 25 light years away from the earth.

Vega, also known as Vega or Lyra? (? Lyrae, the brightest star in Lyra, is about 25 light years away from the earth. Because of its extremely high rotation speed, it is obviously oblate, and the equatorial radius is larger than the polar radius by 19%.

In ancient China? Cowherd and Weaver Girl? In mythology, the weaver girl is the granddaughter of the Emperor of Heaven, so it is also called the sun. In summer in the northern hemisphere, most observers can see Vega with naked eyes near the zenith. It was once the North Star in the northern hemisphere around 12000 BC. Due to precession, it will become the north star again in 13727, when its declination will reach +86? 14'。

It is the first star photographed by human beings outside the sun, the first star with spectral records, and one of the first stars to estimate the distance through parallax measurement. It was once the calibration baseline for measuring luminosity and brightness scale, and it was also one of the stars used by UBV photometry system to define the average value. /kloc-in the 0/9th century, astronomer Thompson designed the concept of apparent magnitude, which is defined as 0 magnitude of each band, namely? Vega magnitude? . Later, everyone thought that Vega's luminosity was changing, so other standards were adopted, and its apparent magnitude was no longer 0. It is the fifth brightest star in the night sky and the second brightest star in the northern hemisphere, second only to arcturus. Like arcturus and Sirius, it is one of the brightest stars near the sun.

So its scientific name is Lyra, a star far away from Altair and close to the earth, and one of the brightest stars near the sun. It belongs to Lyra and is also a bright star of Lyra.

It is one of the most famous bright stars in the summer night sky, so in the west, people also call her? The queen of summer nights? .

Lyra is one of the most splendid constellations in the northern galaxy, named after its appearance resembling the ancient Greek harp. It is one of the 48 constellations listed by Ptolemy, an ancient Greek astronomer, and one of the 88 modern constellations designated by the International Astronomical Union.

Lyra is small, but it is not difficult to identify, because its main star Vega is? Summer triangle? One of the vertices of. Seen clockwise from the north, Lyra is surrounded by Draco, Hercules, Fox and Cygnus. Center position: right ascension 18: 50, declination 36? . There are 53 stars in the constellation whose visual magnitude is brighter than 6, and 8 of them are brighter than 4.
