The Fixed Stars
Epsilon2 Lyrae
Epsilon-2 Lyrae, part of the Double Double
Unnamed, known by its Bayer letter. It stands at about 16° Capricorn (tropical).
One half of the famous Double Double beside Vega.
Epsilon Lyrae stands just northeast of Vega and is celebrated as the Double Double: a wide pair split by the naked eye, each component of which a telescope resolves again into two. Epsilon-2 is the southern star of the wide pair. It carries no old name but is one of the most-shown sights of the small harp. It lies within Abhijit, the nakshatra centered on Vega.
Telescopically the famous Double Double; each wide component resolves into a close pair.
