“ Its two chief stars, (α) and (β) , may be readily recognized west of and above the head of the Scorpion.
The star (ι) Libræ is about 20 degrees northwest of Antares in the Scorpion. Spica in Virgo, a star of the first magnitude, is a little over 20 degrees northwest of (α) Libræ.
A quadrilateral is formed by the stars α, β, γ, ι, which characterizes the constellation.
The star (α) Libræ looks elongated. Binoculars shows that it has a fifth-magnitude companion.
(β) is a pale green star. Its color is very unusual. ”
