What is Tania Borealis

Tania Borealis belongs to the so-called 'leaps of the gazelle', an Arabic sequence of stellar pairs that traced the trail of an animal bounding across the night sky. White and A-class at 137 light-years, she pairs with Tania Australis in the hind leg of Ursa Major. The Western constellation was overlaid on the earlier desert imagery, but both stories still coexist in the same patch of sky.
