g Comae Berenicis and
The Coma Star Cluster


Gamma Comae Berenicis forms the western tip of the constellation's asterism.

More interestingly gamma Com is in the vicinity (although not apparently a part of) the delicate star cluster simply known as The Coma Star Cluster.

Place beta Comae at the eastern edge of your glasses; two close stars (30 and 31) will be on the right side. Now sweep to the west, placing 30 and 31 at the eastern edge. Gamma and the cluster will be sitting on the western edge of your glasses. Move a little further to the west, gathering up all the stars of the cluster: binoculars.

The cluster perfectly fills the field of view in binoculars, making it a delightful object of study. Its stars are roughly 275 light years away, one of the closest star clusters.
     About forty stars form the group, the brightest being 12 Comae. Only a half dozen of the stars are fifth-magnitude, the rest being sixth- or even fainter. Altogether they form a dazzling effect in binoculars.
