Phys.org article presents that nearly all stars are born as binaries. How fun to consider our parent star has a fraternal twin!
The Werner Schmidt Observatory showcases several binaries during star parties. Albireo in the constellation Cygnus displays a contrasting color binary system. Polaris, our North Star, is a multiple star system. Alcor – Mizar systems are both binaries and possibly also binary to one another.

The Alcor Mizar system was reputed to be a test of one’s vision, where being able to see both stars indicated fair vision.
Alcor and Mizar have angular separation of 11′ 49″. Alcor is a binary system — Mizar is a binary system. Alcor and Mizar systems are also thought to be gravitationally bound to one another.
Mizar A – Mizar B have angular separation of 14″ and are easily detectable in all of our telescopes. Components A and B also have component binary stars making this a quadruple system.
Sharing the strong possibility of all stars being born binary with our guests this summer is sure to engage lively discussions.
