The Sun is a as a G2V type star, a yellow dwarf and a main sequence star. Vega is surrounded by a disk of circumstellar dust that may be similar to the solar system’s Kuiper Belt. The star has more than twice the Sun’s mass and radius. An A-type main-sequence star (A V) or A dwarf star is a main-sequence (hydrogen-burning) star of spectral type A and luminosity class V. These stars have spectra which are defined by strong hydrogen Balmer absorption lines. Vega takes its name from the star in the constellation of Lyra, widely described as the most important star in the sky after the sun. Vega is a A0VVAR main sequence star based on the spectral type that was recorded in the Hipparcos star catalogue. Since more massive stars use their fusion fuel more quickly than smaller ones, Vega's main-sequence lifetime is roughly one billion years, a tenth of the Sun's. It is the 5th brightest star in the night sky and, because Earth's pole wobbles over time, it will take Polaris's place as the North Star in 14,000 AD. Ascendant conjunct Vega: Those who are born when this star is rising will be just, upright, and miserly, trained for all duties of the court, avengers of crimes, in charge of public courts and inquiries.

In northern Canada, Alaska, and most of Europe, Vega never sets. Sirian Starseeds. Vega’s spectral type is A (white) and its luminosity class V (main sequence). Deriving chemical composition from spectra by Michael Richmond. Vega is a A0VVAR main sequence star based on the spectral type that was recorded in the Hipparcos star catalogue. Vega measures an option price's value relative to changes in implied volatility of an underlying asset. Vega is a nearby optical spectral type A0V star at about 25 lyrs. Vega is situated in the constellation Lyra, 25 light-years away from Earth, and it is the fifth brightest star in the sky. Vega is a main star in the constellation Lyraand makes up the constellation outline. While the Sun has a central radiation zone at its core covered by a convection zone, Vega has a convection zone at its core that distributes ash from its nuclear reaction. Vega Star Notes - Vega is a blue main-sequence star of spectral type A0V. Vega Star - Facts About Vega | Solarsystemquick.com. While Vega fuses hydrogen, most of the energy at its core comes from the carbon-nitrogen-oxygen (CNO cycle) in which protons combine to form helium with intermediate nuclei of the elements carbon, nitrogen, and oxygen, This process is less efficient than the Sun's proton-proton chain reaction fusion and requires a high temperature of about 15 million Kelvin. Vega is surrounded by a large disc of dust, which suggests that planet forming activity is or has taken place. The convection zone is in equilibrium with the star's atmosphere. Vega was thought to be only a couple of hundred million years old, probably too young for any planets to have spawned life. There are seven main types of stars. Vega (pronounced vee-ga) is 25 light years from Earth. Some of them have come to this planet for their benefit or to support a darker mission. ...

Vega is also known as Alpha Lyrae (α Lyrae, Alpha Lyr, α Lyr), as it is the principle star in the constellation Lyra, the lyre. With the bright stars Deneb and Vega, Altair (Arabic for “flying eagle”) forms the prominent asterism of the Summer Triangle. Vega was born in a Nebula or a huge cloud of gas and dust. Vega is a suspected Delta Scuti variable star, one whose variations in luminosity result from both radial and non-radial pulsations of its surface. If Vega was viewed from above one of its poles, it would appear round. The "Summer Triangle" consists of the bright stars Vega, Deneb, and Altair. Astronomers believe the dust may have resulted from collisions between objects in a debris disk. If it were spinning about 10% faster, it would break apart! Dictionary entry overview: What does Vega mean? She has taught science courses at the high school, college, and graduate levels. Vega will become yet again the northern pole star, but this will happen in the year 13.727. We’ve been fascinated by the Dog Star Sirius since the beginning of time. Vega has been one of the most important stars to humanity since ancient times because it is very bright and easily recognized by its blue color. Procyon B Facts.

Vega is also one of the first stars to have its distance estimated through parallax measurements. It will become the northern polestar by about ad 14,000 because of the precession of the equinoxes. Thanks to its high brightness, Vega is clearly visible when observed from locations with dark skyes, and should be also quite easily visible from light polluted areas. Corrections? Vega's spectral class is A0V, making it a blue-tinged white main sequence star that is fusing hydrogen to helium in its core.
