Mizar, also known as Zeta Ursae Majoris, is a well-known star in the constellation Ursa Major. It is one of the first-known binary star systems discovered, consisting of four stars in total. This system is located approximately 86 light-years away from Earth.

Discovery of Mizar

Mizar was first discovered to be a binary star system by Italian astronomer Giovanni Battista Riccioli in 1650. Later on, in 1889, the secondary companion star, Alcor, also known as 80 Ursae Majoris, was discovered in close proximity to Mizar. The two stars are not physically related but appear close together in the sky, forming a double star.

Mizar-A and Mizar-B

Mizar-A and Mizar-B are the primary stars within the Mizar system. Mizar-A is itself a binary star, consisting of two stars orbiting each other closely. These stars are both larger and hotter than our Sun. Mizar-B, on the other hand, is slightly dimmer but still brighter than most stars in the night sky.

Mizar and Alcor

Mizar and Alcor have been used as a traditional test of visual acuity for centuries. In good viewing conditions, the two stars can be distinguished by the naked eye, making them an interesting pair to observe. However, not everyone can see both stars, as individual eyesight varies.

Overall, Mizar is a fascinating star system that has captured the attention of astronomers and stargazers alike for centuries. Its unique properties and historical significance make it a popular target for observation and study in the field of astronomy.
