Ursa major
The Alcor star which resides in URSA MAJOR, part of the star that makes up the big Dipper, is 81 light years from earth. FYI: Alcor and Mizar are twin stars or double stars which almost line up directly behind each other. However, Alcor is behind Mizar but resides slightly above and to the left of Mizar.
Alkaid, Alcor, Mizar, Alioth, Megrez, Phecda, Dubhe, Merak. that's what I came up with!
Mizar is a quadruplet system of two binary stars in the constellation Ursa Major.All stars are type A which means they are about twice as big as our Sun and about twice as hot. The stars will appear white in colour.
Seven stars make up the Big Dipper - from bowl to handle: 1)Dubhe 2) Merak 3)Phecda 4)Megrez 5)Alioth 6) Mizar (and Alcor) 7) Alkaid
There are seven stars that make up the Big Dipper. They are Alkaid, Mizar-Alcor and Alioth which make up the handle, and Phecda and Megrez which make up the back of the dipper. Merak and Dubhe complete the front end of the dipper.
Ursa Major
the archaic word Mizar means cloak.in astronomy, it refers to a star in the handle of the Big Dipper.its located near Alcor in the the handle of the Big Dipper.And are actually a complex system. Alcor is a binary and Mizar is a quadruple system of two binary stars.

Mizar and Alcor are a pair of stars located in the Big Dipper constellation. They are easily visible to the naked eye and have been used as an eyesight test for centuries. Mizar is actually a quadruple star system, with two pairs of stars orbiting each other.
Mizar is a quadruple system of two binary stars in the constellation Ursa Major.Alcor is a faint companion just to the east. Because it is so faint it is impossible at the moment to gain dimensions of the star.
Ursae Majoris (Mizar) is a quadruple system of two binary stars in the constellation Ursa MajorSo it's impossible to give an answer.

Almost all of them have binary stars. Maybe the most famous "double star" is the second one from the end of Ursa Major's tail (the Big Dipper's handle). The pair of stars there are both bright enough so that good eyes can see both of them. The ancient Arabs called them Mizar and Alcor, the native Americans called them the Horse and his Rider. But this pair is not an authentic "binary star". They're just two unacquainted stars at different distances from us that just happen to be in nearly the same direction. A real 'binary star' is a pair of stars bound in gravitational orbit around each other.

Yes. There are a number of binary stars scattered about the sky, and there is always one visible at night (unless it is cloudy!) In the northern hemisphere, one of the most famous "visual binary" stars - two stars that appear to be next to each other, but which are not gravitationally bound - are the middle "star" in the handle of the Big Dipper. They are Mizar and Alcor. In Roman times, the Legions used these as an eye test; if you could see two stars, then your vision was good enough to be an archer. If you only saw one, then it was not. The star Mizar itself is a true "double star"; two stars orbiting their common center of gravity. Anywhere north of 30 degrees north latitude, these stars (and the Big Dipper itself) are circumpolar; they never set.
No. A Galaxy contains billions of stars whereas a binary star contains only two stars.
