Mizar is one of the most fascinating stars visible in the night sky. Located in the handle of the Big Dipper, within the constellation Ursa Major, it has attracted the attention of astronomers for centuries. What appears to the naked eye as a single star is actually part of a complex multiple-star system.

Together with its nearby companion, Alcor, Mizar forms one of the most famous naked-eye double stars in the sky. Through a telescope, Mizar can be seen as two separate stars. Modern observations have revealed that each of these stars is itself a binary pair, making Mizar a quadruple-star system.

Located approximately 83 light-years from Earth, Mizar holds an important place in astronomical history as one of the first stars discovered to be a telescopic binary. Its unique structure, historical significance, and easy visibility make it a favorite target for stargazers and a fascinating example of the diversity of stellar systems within our galaxy.
