Mizar is located 82.9 Light Years from The Sun. Mizar is in fact, a double star and a quadruple star system with its fainter companion star being Alcor and the four stars it's made of being Mizar Aa, Mizar Ab, ζ1 UMa and ζ2 UMa. 
Mizar Aa
Mizar Aa has a mass of 2.2224 Solar Masses, a radius of 2.4 Solar Radiuses and a Luminosity of 33.3 Solar Luminosities. Mizar Aa has a temperature of 9000 Kelvin and is 370 Million Years Old. 
Mizar Ab
Mizar Ab has a mass of 2.2381 Solar Masses, a radius of 2.4 Solar Radiuses and a luminosity of 33.3 Solar Luminosities. Mizar Ab has a temperature of 9000 Kelvin. So Mizar Ab has clone-like stats to that of Mizar Aa all except for the mass. 
ζ1 UMa
ζ1 UMa has not many stats but does have many other names. These names are GC 18133, HD 116656, HR 5054, PPM 34007 and SAO 28737. 
ζ2 UMa
ζ2 UMa, also known as GC 18134, HD 116657, HR 5055 and SAO 28738, has a surface gravity of 4.40 Centimetre-Gram-Second System of Units and a temperature of 8425 Kelvin.
