Psi3 Aurigae

Psi³ Aurigae is a single,^[9] blue-white hued star in the northern constellation of Auriga. Its name is a Bayer designation that is Latinized from ψ³ Aurigae, and abbreviated Psi³ Aur or ψ³ Aur. This star is dimly visible to the naked eye with an apparent visual magnitude of +5.20.^[3] Based upon an annual parallax shift of 3.66 mas as seen from the Earth,^[2] it is approximately 890 light-years (270 pc) distant from the Sun.
