Answer:

The farthest star we can see with our naked eye is V762 Cas in the constellation of Cassiopeia at 16,308 light years.

Explanation:

Among the 20 brightest stars, the farthest star is Deneb, found in the constellation of Cygnus that is located around 1,550 light years distant from us. However, different estimates of this distance can range between 1,400-3,000 light years.

The farthest star we can see with our naked eye is V762 Cas in the constellation of Cassiopeia at 16,308 light years distant. The naked eye can see up to the 6th magnitude limit, while the brightness of V762 Cas is magnitude 5.8, thus barely placing it in our range of vision.
