title: Pi Ursae Majoris
text: # Pi Ursae Majoris
  
  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.
