Hazel Asher

Nearest * is Proxima Centauri, at a distance of about 4.22 light years.

A triad of *s, in the northern sky, named #alpha#-Centauri (A, B,

Proxima is located between 4.22 and 4.35 light years away from Earth.

Despite the brightness of A and B, Proxima is the closest star at

roughly 4.22 ly away.
