What stars are in the Libra star constellation?

Answer 1

The 4 brightest stars are:

α Librae, Zubenelgenubi ("southern claw"), a visual binary;

β Librae, Zubeneschamali ("northern claw");

γ Librae, Zubenelakrab ("scorpion's claw");

σ Librae, Brachium, an eclipsing variable.

The ones that have bayer designations are:

α (Zubenelgenubi) • β (Zubeneschamali) • γ (Zuben Elakrab) • δ (Zuben Elakribi) • ε • ζ¹ • ζ³ • ζ4 • η • θ • ι¹ • ι² • κ • λ • μ • ν • ξ¹ • ξ² • ο • σ (Brachium, γ Sco) • τ • υ

The stars with flamsteed numbers are: (e.g. 51 Pegasi, but without the Pegasi)

2 • 3 • 4 • 5 • 7 (μ) • 8 (α¹, Zubenelgenubi) • 9 (α², Zubenelgenubi) • 10 • 11 • 12 • 13 (ξ¹) • 15 (ξ²) • 16 • 17 • 18 • 19 (δ, Zuben Elakribi) • 20 (σ, Brachium) • 21 (ν) • 22 • 23 • 24 (ι¹) • 25 (ι²) • 26 • 27 (β, Zubeneschamali) • 28 • 29 (ο) • 30 • 31 (ε) • 32 (ζ¹) • 33 • 34 (ζ³) • 35 (ζ4) • 36 • 37 • 38 (γ, Zuben Elakrab) • 39 (υ) • 40 (τ) • 41 • 42 • 43 (κ) • 44 (η) • 45 (λ) • 46 (θ) • 47 • 48 • 49 • 50

Nearby stars are:

33 G. (Gliese 570) • HN (Gliese 555) • HO (Gliese 581) • 2MASS 1507-1627 • Gliese 595

Libra is known to have 5 stars within 10 parsecs (32.62 lightyears).

Libra is home to the star Gliese 581, which has a planetary system consisting of at least 6 planets, including Gliese 581 g, the best candidate planet for human habitability and extra-solar life yet discovered, Gliese 581 c, the first Earth-like extrasolar planet to be found within its parent star's habitable zone, Gliese 581 d, discovered in 2007 to be another Earth-like planet, and Gliese 581 e, the smallest mass exoplanet orbiting a normal star, all of which are of significance for establishing the likelihood of life outside of the Solar System. The family of candidate habitable planets was extended in late September 2010 to include Gliese 581 g, a tidally locked planet in the middle of the habitable zone, and currently the most likely discovered exoplanet to be capable of supporting life.

Answer 2

Some of the stars in the Libra constellation include Alpha Librae (Zubenelgenubi), Beta Librae (Zubeneschamali), and Gamma Librae (Zubenelakrab). These stars are part of the scales that represent the symbol of Libra, the scales.
