Vega was the northern pole star around 12,000 BCE and will be so again around the year 13,727, when its declination will be +86° 14′. [19] Vega was the first star other than the Sun to have its image and spectrum photographed. [20] [21] It was one of the first stars whose distance was estimated through parallax measurements.
Despite its massive size, astronomers calculate that Vega is only about one-tenth the age of our sun and is likely approaching middle age in its stellar life cycle. Given that our sun is roughly 4.5 billion years old, Vega is just 450 million years old and may only live another 450 million years.
- Vega is so important because it's the fifth brightest star in the night sky. Also, it used to be the North Pole star around 12,000 B.C.E. and wil...
- Vega is a massive star, about twice as large as our own sun.
- According to Encyclopaedia Britannica , Vega is spectral type A and luminosity class V.
- Considering it is 25 light-years away from Earth, Vega is in the Milky Way galaxy.
- To find Vega in the night sky, look for the cross formed by stars in the constellation Cygnus, the Swan. Vega is the bright star under one of the...

For thousands of years, the star Vega has been observed by humans, with records found in ancient Chinese, Arabic, and Greek astronomy. In recent history, astronomers chose it as a reference point for measuring other stars’ color and apparent brightness. Today, scientists are studying Vega to learn about the early stages of stellar evolution and to ...
Official name: Alpha Lyrae, α LyrAlternative names: Wega, Alf Lyr, Al-Waqi'Catalog designations: HIP 91262, HR 7001, HD 172167, TYC 3105-2070-1Constellation: LyraVega is the brightest star of the Lyra constellation, one of the smallest constellations in the night sky. It is also part of a larger asterism known as the Summer Triangle. It’s easy to find Vega and other stars with stargazing apps like Sky Tonight. Read on to get the step-by-step guide.
Vega was mentioned in many ancient myths, including Chinese, Japanese, Indian, Greek, and Arabic. Some of these myths have left their marks on the name of the star and its constellation.
The first star to be photographed
On July 17, 1850, Vega became the first star other than our Sun to be photographed. Astronomers James Adams Whipple and William Cranch Bond captured the star using the daguerreotype technique. They focused Vega's light on a photosensitive silver-plated copper sheet and exposed it for about 20 minutes using the 15-inch refractor at Harvard College Observatory. Over two decades later, in August 1872, the star made history again. This time, amateur astronomer Henry Draper photographed Vega's spe...
Vega may have a planet
In recent years, astronomers discovered that Vega may have a large asteroid belt similar to our own Solar System’s Asteroid and Kuiper belts. The data revealed two distinct belts around Vega: a warm inner belt and a cool outer belt, with a gap in between. Scientists believe that this gap could be home to multiple planets orbiting the star. A study published in The Astronomical Journalsuggests that evidence has been found for at least one such planet. This planet is believed to be as large as...
Our past and future North Star
Our modern Polaris seems motionless, but it slowly shifts across the sky in a circuit that takes about 26,000 years, giving way to other stars near the north celestial pole. This motion is due to the precession of the Earth's axis. Around 12,000 BCE, the Paleolithic people observed Vega as the North Star instead of Alpha Ursae Minoris. And in the future, by around 13,600, Vega will become the North Star again.
Vega is one of the brightest stars in the sky and plays a unique role in astronomy. For a long time, it was the absolute reference for the brightness and color of stars, and now it continues to be studied because it may have a planet. In 13,000 years, it will be the new North Star, the brightest of the following millennia. Get to know this brillian...
Sep 7, 2022 · Vega is a bluish-white, class A 0 main sequence star that's 2.1 times as massive as the Sun and about 2.5 times as big located 25 light-years away. Classified as an A 0V star, Vega appears brilliant white with the naked eye. Although both the Sun and Vega are on the main sequence, the Sun is about 10 times older.
Nov 9, 2018 · The star is only about 450 million years old, which makes it a youngster compared to our own solar system (which is 4.6 billion years old). Studies of Vega help astronomers learn more about solar ...
Jan 8, 2020 · It is the second star to be photographed, and the first to have its spectrum recorded. It was photographed in 1850. Vega is only 25 light-years away from the Sun. It has a tenth of the age of our Sun, and it is 2.1 times more massive. Vega is a variable star thus it changes its brightness.

Nov 5, 2023 · The legend is more than 2,600 years old. It also inspired the Tanabata festival in Japan and the Chilseok festival in Korea. The Tanabata festival celebrates the meeting of Orihime (Vega) and Hikoboshi ( Altair ), while the Korean event is associated with the folktale of Jiknyeo (the weaver girl) and Gyeonwu (the herder).
