Lambda Ursae Majoris (λ UMa / λ Ursae Majoris) is a star in the constellation Ursa Major. It also has the proper names Tania Borealis (former Tania borealis[1]) meaning "the Northern (star) of Tania." The word Tania comes from the Arabic phrase (al-Qafzah) al-Thāniyah meaning "the Second (Leap)" (the distinctions "northern" (borealis) is added in Latin), and Alkafzah Borealis[citation needed]. With Mu Ursae Majoris, they were Chung Tae （中台）, the Middle Dignitary, in Chinese astronomy.[2]
