Eps-2

Its story

Epsilon-2 Lyrae is part of the famous Double Double asterism, a quadruple system of white stars that splits in a modest telescope near Vega. About one hundred and fifty-five light-years away, its two main components revolve slowly around one another while each conceals an even tighter pair. It is one of the objects most often shown to those just beginning to observe the sky with their own instrument.
