It is a G-type star.
Considered a binary, possibly quintuplet, star system Alpha Librae has two bright main stars. The brighter of the two is a dwarf star of spectral type A3 and its companion is a yellow-white dwarf of spectral type F4.
Upsilon Librae is a binary star system located in the constellation Libra. The primary component is a G-type giant star, while the secondary is a smaller, cooler star. Upsilon Librae is notable for its relatively high luminosity and is approximately 40 light-years away from Earth.
Zubeneschamali (Beta Librae) is the brightest star in the constellation Libra. I has an apparent magnitude of 2.61.
The main stars in the constellation Libra include Zubeneschamali (Beta Librae), Zubenelgenubi (Alpha Librae), and Zubenelhakrabi (Gamma Librae). These stars form part of Libra's distinctive scale-like pattern.
Beta Librae, also known as Zubenelgenubi, has an effective surface temperature of approximately 4,700 Kelvin. This temperature categorizes it as a K-type giant star, which gives it a characteristic orange hue. Its cooler temperature compared to the Sun contributes to its distinct color and spectral classification.
Alpha Librae is the second brightest star in the constellation Libra.It has an absolute magnitude of +3.28It has an apparent magnitude of +5.15
Beta Librae has a spectral class of B8 showing it has the colour of Blue White. However, it is the only star to appear, to some people, as green because of an optical illusion. See related link.
Alpha Librae has a temperature of around 9,600 K, Gamma Librae has a temperature of around 5,000 K, and Sigma Librae has a temperature of around 6,000 K. Gamma Librae appears white in color, while Sigma Librae appears yellow-orange.
Zuben-el-Akrab (Gamma Librae, also corrupted as Zuben Hakraki ) is a star of spectral type K0 III; an extremely luminous supergiant of the orange variety.
If by primary, brightest is meant, Zubeneschamali (Beta Librae) is the brightest star in the constellation Libra with an apparent magnitude of 2.61.
Beta Librae, also known as Zubenelgenubi, has an absolute magnitude of approximately +0.5. This value indicates its intrinsic brightness, allowing astronomers to compare its luminosity to other stars regardless of their distance from Earth. Beta Librae is a relatively bright star located about 77 light-years away in the constellation Libra.
Gamma Librae is a very faint orange color.
