There is no known star named "Nahn". It's possible you might have misspelled the name or are referring to a fictional star from a book or movie.

To help me find the star you're looking for, please provide me with more information:

* Is it a real star?

* If it's fictional, where is it from? (e.g., a book, movie, TV show)

* Do you know any other details about it? (e.g., constellation, brightness, color)

With more information, I can help you identify the star you're interested in.
