Melotte 111 (Mel 111) - Coma [Berenices] Star Cluster

Introduction | Map | Own Observations | References

On this page I collect my observations of the open star cluster Mel 111 (Coma Berenices star cluster) in the constellation Coma Berenices.



The open star cluster Mel 111 in the constellation Coma Berenice, also known as Coma [Berenices] star cluster, has been known since antiquity and makes up the main part of Berenike's hair. Following the Hyades, it is the second largest stars cluster in the sky (3.5 °). I was able to see the shimmering star cluster with the naked eye, and it should only be looked at with very low magnification.

Size: 3.5° (Stoyan)
Distance: 290 light years
Ranking: *** (Stoyan)
