There are two stars with the Bayer designation ω Scorpii (omega Scorpii):

They are separated by 0.24° on the sky, which is far enough apart to be individually resolved with the naked eye.[1] The two stars are not physically associated with each other,[2] and thus only form an optical pair. ω Scorpii also has the traditional name Jabhat al Akrab,[2] which is derived from the Arabic جبهة العقرب jabhat[u] al-caqrab meaning "[The] forehead of the scorpion". For the Chinese, the pair were known as Kow Kin, meaning a Hook and Latch.[3]
