Psi Ursae Majoris (Psi UMa, ψ Ursae Majoris, ψ UMa) is a
Chinese constellation
).
The
K-type star.[11]
Psi Ursae Majoris is a member of the
thin disk population of the Milky Way. It is following an orbit through the galaxy with a low eccentricity of 0.02 that will carry it between 26.5–27.8 kly (8.1–8.5 kpc) from the Galactic Center. The low inclination of its orbit means the star will only stray 130 ly (40 pc) from the galactic plane.[8]
