  Mizar
Mizar is a star in the constellation Ursa Major, lying just at the corner of the Big Dipper's handle.
Mizar B and Alcor were both later found to be spectroscopic doubles as well.
Mizar is also the name of a language for writing strictly formalized mathematical definitions and proofs, for a computer program to check these proofs, and for a library containing definitions and theorems.

 Mizar (Zeta Ursae Majoris)
Mizar is also famous as the first known true binary, in which a pair of stars that orbit each other, were seen telescopically, by Giovanni Riccoli in 1650.
Mizar A was the first spectroscopic binary to be discovered, in 1189.
The Mizar quartet moves through space at a similar speed and direction to Alcor, but measurements by the Hipparcos satellite suggest that Mizar and Alcor are separated by 2-3 light-years –; too far for the systems to be physically associated.

 Mizar   (Site not responding. Last check: 2007-10-10)
One of the most famed stars of the sky, second magnitude (2.06) Mizar, 78 light years away, is the Zeta star of Ursa Major, the Greater Bear, the second star in from the end of the handle of the
Found to be double in 1650, Mizar is a prime target for someone with a new telescope, as the components are an easy 14 seconds of arc apart (at least 500 astronomical units), the two taking at least 5000 years to make their orbit about each other.
Mizar is thus actually a quartet of stars, a double-double.

 Mizar   (Site not responding. Last check: 2007-10-10)
Mizar B is also a type A main sequence star separated from A by 14 arc seconds, which corresponds to a projected separation of 340 AU or more than 8 times the diameter of the orbit of planet Pluto.
Spectral analysis reveals Mizar A itself to be a binary star consisting of two main sequence A2V stars orbiting around each other with a period of 20.5 days in a rather elliptical orbit having a semimajor axis of about 27 million miles.
According to Burnham, Mizar is part of a star cluster including at least 16 other stars from the Ursa Major area of the sky, as well as Alioth, Merak, Alcor, Phecda, and Megrez in the Big Dipper.

 Big Dipper
Mizar, at a distance of 78 light years from the Sun, and Alcor at 81 light years, while appearing to be a double star, are actually only an optical double.
However, Mizar and Alcor are members of the nearest star cluster to the sun, the Ursa Major moving cluster, Collinder 285.
Between Mizar and Alcor is a fourth star, Sidus Ludoviciana, shining at magnitude 8, which is a field star that is not even part of the Ursa Major cluster.

 Mizar
Mizar, a small ice‑strengthened cargo ship built for the Military Sea Transportation Service, completed her shakedown in time to join Arctic operations in the summer of 1958, resupplying the Dew line and military bases on Greenland and in the Canadian Arctic.
With a load of helicopters and provisions she joined TG 43.1 at Littleton, New Zealand, early in November and steamed to McMurdo Bound.
Mizar, loaded with sensitive instruments, and with her additional accommodations for scientists frequently occupied, continues to serve science and the Navy.

 Mizar Through a Galilean Telescope
Mizar B should not be confused with Alcor, a star of similar brightness about 12 arc-minutes from Mizar, far outside the small field shown here.
A New View of Mizar), Galileo estimated the separation between the centers of Mizar A and B as 15 arc-seconds and the diameters of the images as 6 and 4 arc-seconds with a gap of 10 arc-seconds between them.
If Mizar A were indeed only 300 solar distances away its annual wobble relative to a truly distant star should have been an easily observable ±12 arc-minutes; and Mizar B, at 450 solar distances (3/2 times farther than Mizar B), would have been expected to show an annual parallax of ±8 arc-minutes.

 Mizar.
The "hill Mizar" of the 42d Psalm sometimes is wrongly associated with this, the original Hebrew word mis'ar being better rendered in the Psalter, from Coverdale's version, as "the little hill," i.e.
This star, Mizar (zeta), also was the Arabic 'Anak al Banat, the "Necks of the Maidens", referring to the "Mourners at the Bier"; or perhaps this should be rendered "the Goat of the Mourners," for in some editions of Ulug Beg's Tables it was written Al Inak, — correctly Al 'Inz.
The reputation of Mizar, if it is in maximal position in a mundane map, is that of being connected with fires of a catastrophic extent and mass calamities.

 A New View Of Mizar
Compare the first reliable measurement of Mizar made by James Bradley and reduced to the epoch 1755 – position angle 143.1 degrees and angular distance 13.88 arcseconds, with the result of the Hipparcos satellite: 152 degrees and 14.43 arcseconds (epoch 1991.25).
Although Mizar A was not the first spectroscopic binary to be measured by this innovative technique – this priority belongs to bright Capella – it was observed by the first (and for many years also the last) functional astronomical interferometer, the 20-foot constructed by Michelson and Francis G. Pease at Mount Wilson.
Mizar A's stars orbit each other with period of 20 days 12 hours 55 minutes and 13 seconds at a distance which changes from 16 to 54 million kilometers.
