Izar is a double star system. The B component is 2.19 magnitudes dimmer than A and separated from it by 2.867 sec of arc, corresponding to a projected distance of 184 AU (4.7 times the radius of the solar system out to Pluto.) ...
Izar is the best and can be separated into it's component stars,an orange giant and a blue-green companion star, in a telescope with a 75mm(about 3 inches) aperture. NGC5466 is a globular cluster visible in most telescopes.
Next down in brightness is second magnitude (2.39) Izar (Epsilon Bootis), which ranks as one of the finest telescopic double stars in the sky. Lying right next to Izar, only 0.
The double epsilon Boo (a 9372), with the beautiful name Izar of Pulcherrima, is a glorious pair, but difficult to resolve. The K0 giant of 2.7 mag and its A2 main sequence companion of 5.
IZAR (Epsilon Boo) Mufrid (Eta Boo) Asellus Primus (Theta Boo) Asellus Secondus (Iota Boo) Asellus Tertius (Kappa 2 Boo) Alkalurops (Mu 1 Boo) Merga (38 Boo) Some say that Boötes is the most ancient constellation in the sky.
Epsilon Bootes, also known as Izar, is a beautiful double star made up of a mag 2.5 primary and a mag 5.0 secondary star. The pair have beautifully contrasting colors of yellow and green.
[878] epsilon Bootis, Izar ("veil") or Pulcherrima ('loveliest'), is a binary star composed of a bright orange giant and a main sequence star. Its other traditional names are Mirak ("the loins") and Mizar.

The constellation Corona Borealis is found nearly midway between Arcturus and Vega; a little closer to the first of these stars. From Arcturus move up to Izar (epsilon Bootis) and then east fifteen degrees to alpha CrB.
