Alpha
Alpha (uppercase, lowercase) is the first letter of the Greek alphabet.
Angular diameter
The angular diameter, angular size, apparent diameter, or apparent size is an angular distance describing how large a sphere or circle appears from a given point of view.
See Alpha Librae and Angular diameter
Angular distance
Angular distance or angular separation is the measure of the angle between the orientation of two straight lines, rays, or vectors in three-dimensional space, or the central angle subtended by the radii through two points on a sphere.
See Alpha Librae and Angular distance
Apparent magnitude
Apparent magnitude is a measure of the brightness of a star or other astronomical object.

Constellation
A constellation is an area on the celestial sphere in which a group of visible stars forms a perceived pattern or outline, typically representing an animal, mythological subject, or inanimate object.
See Alpha Librae and Constellation
Double star
In observational astronomy, a double star or visual double is a pair of stars that appear close to each other as viewed from Earth, especially with the aid of optical telescopes.
See Alpha Librae and Double star
Durchmusterung
In astronomy, Durchmusterung or Bonner Durchmusterung (BD) is an astrometric star catalogue of the whole sky, published by the Bonn Observatory in Germany from 1859 to 1863, with an extension published in Bonn in 1886.

Ecliptic
The ecliptic or ecliptic plane is the orbital plane of Earth around the Sun.
Epoch (astronomy)
In astronomy, an epoch or reference epoch is a moment in time used as a reference point for some time-varying astronomical quantity.

Gamma Librae
Gamma Librae (γ Librae, abbreviated Gamma Lib, γ Lib) is a suspected binary star system in the constellation of Libra. Alpha Librae and Gamma Librae are bright Star Catalogue objects, Henry Draper Catalogue objects, Hipparcos objects, Libra (constellation) and stars with proper names.
See Alpha Librae and Gamma Librae
