Pi Ursae Majoris
  Location of Pi¹ and Pi² Ursa Major (circled) | |
The Bayer designation Pi Ursae Majoris (π UMa, π Ursae Majoris) is shared by two stars in the constellation Ursa Major:
- Pi¹ Ursae Majoris (3 Ursae Majoris)
- Pi² Ursae Majoris (4 Ursae Majoris)
They are separated by 0.70° in the sky. They are sometimes given the name Muscida, which can also refer to ο Ursae Majoris.
The two stars, Pi¹ and Pi² together, are considered an optical double star. They are not a binary star, in that they are not gravitationally linked, but they are close to each other as seen in the sky, and so are optically associated.
