Many stars come in pairs.
Some come in pairs in different ways. Unfortunately, it is not all that tidy, as Algorab used to belong to the star now called Gienah. Though the third brightest star in the constellation, it was called Delta by Bayer. The two stars, however, are paired only as the raven's wings and as pointers. Gienah is 165 light years away, whereas Algorab is a mere 88, so the two really have nothing to do with each other.
