Here's why:

* 1 parsec is roughly 3.26 light-years.

* The nearest star to our Sun is Proxima Centauri, located approximately 4.24 light-years away.

Therefore, Proxima Centauri is the closest star to our Sun, and it is located further away than 1 pc.

While there are other stars within a few light-years of our Sun, none are within 1 parsec (3.26 light-years).
