Collinder 69

Cr 69

The stars that form Orion's 'head' are part of an open star cluster identified as Collinder 69. The brightest of these is Heka (also known as Meissa), but the cluster contains numerous other stars in addition. The cluster seems to be relatively young, in astronomical terms, and probably formed no more than ten million years ago. Remnants of the nebulous material from which it formed can still be seen between the cluster's stars.
