Epsilon Lyrae
About this celestial object
Epsilon Lyrae, the famed double‑double near Vega, tests the resolving power of any instrument.
Epsilon Lyrae comprises two pairs of close double stars—under good magnification, two points of light become four. The system is a classic for stargazers.
In the wide field, the geometry reveals itself through the companions’ symmetric arrangement in the quiet stellar surroundings.
