The constellation Libra marked on a naked eye view. Overall, there are 83 stars within the constellation's borders brighter than or equal to apparent magnitude 6.5. [a] [2] The brightest stars in Libra form a quadrangle that distinguishes it for the unaided observer. Traditionally, Alpha and Beta Librae are considered to represent the scales ...

The two brightest components of Alpha Librae form a double star moving together through space as common proper motion companions. They are separated in the sky by an angular distance of 231" (3'51"). The position angle of the companion is 314 degrees. The brighter of the two is a white star of spectral type A3, with an apparent magnitude of 2.8 ...
Beta Librae (β Librae, abbreviated Beta Lib, β Lib), formally named Zubeneschamali / z uː ˌ b ɛ n ɛ ʃ ə ˈ m eɪ l i /, [10] [11] is (despite its 'beta' designation) the brightest star in the zodiac constellation of Libra. From parallax measurements, its distance can be estimated as 185 light-years (57 parsecs) from the Sun. [1]
ζ 2 Librae (abbreviated Zeta 2 Librae, Zeta 2 Lib, ζ 2 Lib), also known as 33 Librae, is a variable star in the constellation Libra. It is approximately 261 light-years away from the Sun. [2] Zeta 2 Librae does not have an HR number, although it is included in the Bright Star Catalogue Supplement. [3] [4]
Epsilon Librae (ε Lib) is the Bayer designation for a binary star system in the zodiac constellation Libra.With an apparent visual magnitude of 4.922, [2] it is bright enough to be seen with the naked eye.
Such multiple star systems are indicated by parentheses showing the individual magnitudes of component stars bright enough to make a detectable contribution. For example, the binary star system Alpha Centauri has the total or combined magnitude of −0.27, while its two component stars have magnitudes of +0.01 and +1.33.
HD 139139 (also known as EPIC 249706694) is likely part of a bound pair system of main sequence stars about 350 light-years (110 parsecs) away from Earth in the constellation Libra. HD 139139 is a G-type main-sequence star, a little larger and more luminous than the Sun, and at an almost identical temperature
