The “green” star: Many observers of Beta Librae claim that the white star appears as a shade of green. Scientists have deemed that a star can only appear green when close companions of red stars; however, since Beta Librae does not fit into this category, observers are left to make their own judgments.

Modern measurement: The word ’libra’ is responsible for our abbreviation of the pound weight, “lb.” Scales were used to measure a pound of salt, a Roman soldier’s pay. The British symbol for pound is also derived from the word.

Libra in literature: Chaucer mentions Libra in his “Prologue to the Parson’s Tale.” Alluding to Christ’s Passion, Libra ascends as the pilgrims near their destination.
