Vega is the brightest star in the constellation Lyra, the fifth brightest star in the night sky and the second brightest star in the northern celestial hemisphere, after Arcturus.

It is a relatively close star at only 25 light-years from Earth, and, together with Arcturus and Sirius, one of the most luminous stars in the Sun's neighborhood - wikipedia

Vega has been extensively studied by astronomers, leading it to be termed “arguably the next most important star in the sky after the Sun.” Vega was the northern pole star around 12,000 BCE and will be so again around the year 13,727 when the declination will be +86°14'. Vega was the first star other than the Sun to be photographed and the first to have its spectrum recorded. It was one of the first stars whose distance was estimated through parallax measurements. Vega has served as the baseline for calibrating the photometric brightness scale, and was one of the stars used to define the mean values for the UBV photometric system.

Based on an observed excess emission of infrared radiation, Vega appears to have a circumstellar disk of dust. This dust is likely to be the result of collisions between objects in an orbiting debris disk, which is analogous to the Kuiper belt in the Solar System. Stars that display an infrared excess because of dust emission are termed Vega-like stars.

# Cultural Significance

The name Wega (later Vega) comes from a loose transliteration of the Arabic language meaning "falling" or "landing", via the phrase "the falling eagle".

The term "Al Nesr al Waki" appeared in the Al Achsasi al Mouakket star catalogue and was translated into Latin as ''Vultur Cadens'', "the falling eagle/vulture".

The constellation was represented as a vulture in ancient Egypt, and as an eagle or vulture in ancient India.

The Arabic name then appeared in the western world in the Alfonsine Tables, which were drawn up between 1215 and 1270 by order of Alfonso X.

Among the northern Polynesian people, Vega was known as ''whetu o te tau'', the year star. For a period of history it marked the start of their new year when the ground would be prepared for planting. Eventually this function became denoted by the Pleiades.<ref name=jps28_18/>

In Chinese mythology, there is a love story of Qi Xi () in which Niu Lang (, Altair) and his two children (β (Beta Aquilae) and γ Aquilae (Gamma Aquilae)) are separated from their mother Zhi Nü (, lit. "Weaving Girl", Vega) who is on the far side of the river, the Milky Way.<ref name=wei_yue_tao2005/> However, one day per year on the seventh day of the seventh month of the Chinese lunisolar calendar, magpies make a bridge so that Niu Lang and Zhi Nü can be together again for a brief encounter. The Japanese Tanabata festival, in which Vega is known as ''orihime'' (織姫), is also based on this legend.<ref name=kippas1919/>

In Hindu mythology, Vega is called Abhijit. The author of Mahabharat, Maharshi Vyas, mentions in the chapter ''Vana Parva'' (Chap. 230, Verses 8–11): "Contesting against Abhijit (Vega), the constellation Krittika (Pleiades) went to "Vana" the summer solstice to heat the summer. Then the star Abhijit slipped down in the sky." P. V. Vartak suggests in his book, ''The Scholarly Dating of Mahabharat'', that the "slipping of Abhijit" and ascension of Krittika (Pleiades) might refer to the gradual drop of Vega as a pole star since 12,000&nbsp;BC. Vega is expected to become Earth's pole star by the year 26,000 by some estimates.<ref name=vartak20_75/>
