NotesA faint sixth-magnitude star lying slightly northward of Meissa, the star that marks the head of Orion. HR 1883 is a blue giant and a spectroscopic binary, with a comparatively massive companion revealed through shifting patterns in the star's spectrum.

HR 1883 lies beyond Meissa and the Lambda Orionis Cluster at the head of Orion (Meissa is the star that can be seen shining on the lower edge of this image). Meissa and its cluster lie more than a thousand light years from the Sun, but HR 1883 is more distant still, at some 1,700 light years from Earth. Imagery provided by Aladin sky atlas
