context_page_description: Mu Boötis, Latinized from μ Boötis, consists of a pair of double stars in the northern constellation of Boötes. The primary pair, components Aa, are designated μ¹ Boötis and have an angular separation of 0.08″. The secondary, consisting of components BC, is designated μ² Boötis and they have a separation of 2.2″. The two double star systems are separated by 107″, with matching parallaxes and proper motions, suggesting they form a system. However, compents BC have a different chemical composition compared to Aa, indicating this may instead be a close encounter between two binary systems.
  Mu Boötis had the traditional name Alkalurops, although the International Astronomical Union now regards that name as only applying to μ¹ Boötis.
  Mu Boötis is approximately 121 light-years from the Sun.
