Saiph, also designated Kappa Orionis (κ Orionis, abbreviated Kappa Ori, κ Ori) and 53 Orionis (53 Ori), is the sixth-brightest star in the constellation of Orion. Of the four bright stars that compose Orion’s main quadrangle, it is the star at the south-eastern corner.

Many of the other bright stars in Orion (for example, the belt stars) are at the same distance as Saiph. Probably Saiph and these other stars formed out of the molecular clouds astronomers have found in Orion.All three are at the same distance from us and, with Rigel and Meissa, probably formed at about the same time some ten million years ago.
