Vega - α Lyrae (alpha Lyrae)

Vega, also designated as α Lyrae (alpha Lyrae), is a variable and multiple hypergiant star in the constellation of Lyra.

Vega visual magnitude is 0.03, making it the 5th brightest star in the sky. 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.

Digitized Sky Survey image of Vega

The image below is a photograph of Vega from the Digitized Sky Survey 2 (DSS2 - see the credits section) taken in the red channel. The area of sky represented in the image is 0.5x0.5 degrees (30x30 arcmins). The proper motion of Vega is 0.202 arcsec per year in Right Ascension and 0.286 arcsec per year in Declination and the associated displacement for the next 1000 years is represented with the red arrow.
