In order of brightness,
Vega (α Lyrae) is the bright star at the upper left of the image. It is the brightest star in Lyra, the fifth-brightest in the night sky, and the second-brightest visible in the Northern Hemisphere. It is a blue-white giant star about 25 light years from the Sun. It has about twice the mass and a little over twice the size of the Sun. The name comes from the Arabic word wāqi' meaning "falling" or "landing".
Sulafat (γ Lyrae) is the second brightest star, a blue giant star about 620 light years from Earth. It is about 6 times as massive and 13 times the size of the Sun. Its name comes from the Arabic word al-sulḥafāt meaning "turtle", connecting lyres with their material: tortoiseshell.
Sheliak (β Lyrae) is a multiple star system, consisting of six stars at a distance of about 960 light years from Earth. The primary star is a blue giant about 3 times the mass and 15 times the size of the Sun. The name comes from the Arabic word šiliyāq which was one of the names for Lyra in Arabic astronomy.
δ² Lyrae is a red supergiant star about 770 light years from the Sun. Although it is only 4.5 times as massive, it is almost 300 times the size of the Sun!
ζ¹ Lyrae is a binary star system about 156 light years from Earth. The primary is a blue-white chemically peculiar star about 2.5 times the size and mass of the Sun.
ε² Lyrae is a binary star system that forms one half of "the Double Double". This system lies about 156 light years from Earth. The primary is a blue-white giant star about 2.1 times the mass of the Sun.
ε¹ Lyrae is another binary system and the other half of "the Double Double". This system is marginally more distant at 162 light years away. The primary is a blue-white star about twice the mass of the Sun.
δ¹ Lyrae is the optical companion to δ² Lyrae; the two systems are unrelated. δ¹ Lyrae is a binary star system composed of a blue star and an orange giant. The entire system is about 1,160 light years away.
Finally, ζ² Lyrae is a single white-hued star about 158 light years from the Sun. It has about 1.75 times the mass of the Sun and is about twice as big.
