What constellation is Vega in?

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

In the ancient myth of "Cowherd and Weaver Girl", Weaver Girl is the granddaughter of the Emperor of Heaven, so it is also called Tiansun. 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, and its declination will reach +86 14'. It is the first star outside the sun photographed by human beings, the first star with spectral records, and one of the first stars to estimate the distance through parallax measurement. It used to be the calibration baseline of photometric scale and one of the stars used by UBV photometric system to define the average value. /kloc-in the 9th century, astronomer Thompson designed the concept of apparent magnitude, which is defined as 0 in each band and called "Vega magnitude". Later, people 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.
