What is Lambda Librae

Lambda Librae burns 310 light-years away as a hot blue-white B-type star, faintly variable. The celestial scales —once held by the Greeks as the claws of Scorpius— were carved out as an independent constellation by the Romans to honour justice. Within that symbolic figure, Lambda occupies a quiet place, far from the greenish glow of Zubeneschamali and the reddish Zubenelgenubi.

Where it is and when to see it

Lambda Librae lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is May, when it culminates around midnight.

From London it culminates about 18° above the horizon.
