There is no star known as "Wezn." It's possible you might be thinking of a different star, or the name might be misremembered or misspelled.

To find the distance to a specific star, you can:

* Use an online star catalog: Sites like Simbad (https://simbad.u-strasbg.fr/simbad/) or the International Astronomical Union's website (https://www.iau.org/) provide comprehensive data on known stars, including their distances.

* Use a stargazing app: Many apps like Stellarium, SkySafari, or Star Walk allow you to search for stars and provide information about their distances.

Please provide more information if you have it, like the constellation the star might be in or any other details you remember, and I might be able to help you find the star you're looking for.
