Vega is the brightest star in the northern constellation of Lyra. It has the Bayer designation α Lyrae, which is Latinised to Alpha Lyrae and abbreviated Alpha Lyr or α Lyr. This star is relatively close at only 25 light-years from the Sun, and, together with Arcturus and Sirius, one of the most luminous stars in the Sun's neighborhood. It is the fifth-brightest star in the night sky, and the second-brightest star in the northern celestial hemisphere, after Arcturus. 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 BC and will be so again around the year 13,727, when its 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 functioned as the baseline for calibrating the photometric brightness scale and was one of the stars used to define the zero point for the UBV photometric system.



Vega is only about a tenth of the age of the Sun, but since it is 2.1 times as massive, its expected lifetime is also one tenth of that of the Sun; both stars are at present approaching the midpoint of their life expectancies. Vega has an unusually low abundance of the elements with a higher atomic number than that of helium. Vega is also a variable star that varies slightly in brightness. It is rotating rapidly with a velocity of 236 km/s at the equator. This causes the equator to bulge outward due to centrifugal effects, and, as a result, there is a variation of temperature across the star's photosphere that reaches a maximum at the poles. From Earth, Vega is observed from the direction of one of these poles.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 due to dust emission are termed Vega-like stars.

Informations

Lansing is the capital of the U.S. state of Michigan. It is mostly in Ingham County, although portions of the city extend west into Eaton County and north into Clinton County. The 2010 Census placed the city's population at 114,297, making it the fifth largest city in Michigan. The population of its Metropolitan Statistical Area (MSA) was 464,036, while the even larger Combined Statistical Area (CSA) population, which includes Shiawassee County, was 534,684. It was named the new state capital of Michigan in 1847, ten years after Michigan became a state. The Lansing metropolitan area, colloquially referred to as "Mid-Michigan", is an important center for educational, cultural, governmental, commercial, and industrial functions.



Neighboring East Lansing is home to Michigan State University, a public research university with an enrollment of more than 50,000. The area features two medical schools, one veterinary school, two nursing schools, and two law schools. It is the site of the Michigan State Capitol, the state Supreme Court, the Court of Appeals, a federal court, the Library of Michigan and Historical Center, and headquarters of four national insurance companies. Lansing is the only U.S. state capital (among the 47 located in counties) that is not also a county seat. The seat of government of Ingham County is Mason, but the county maintains some offices in Lansing.
