Lyra (pronounce /ˈlaɪrə/, Latin: lyre) is one of the 48 constellations listed by Ptolemy, and is one of the 88 modern constellations recognized by the International Astronomical Union. Lyra is a small constellation, but its principal star, Vega, is one of the brightest in the sky. Lyra took its name from the stringed musical instrument well known for its use in Classical Antiquity and still in some areas of Greece.
