Many of the objects we see in space are beautiful objects with extremely beautiful names. The open star cluster Messier 6 is one such object. It is also called the Butterfly Cluster because this star cluster resembles the open wings of a butterfly. And indeed, these celestial gems give beautiful views and experiences of the deep universe. This star cluster is located in the direction of the constellation Scorpio, and is approximately 2,000 light-years from Earth.
With 4.2 apparent magnitude – Messier 6 can also be seen with the naked eye, but it is best seen when viewed with binoculars or a small telescope. With a small telescope, approximately 80 stars brighter than magnitude 11 can be seen. The brightest star in this open star cluster is the orange giant – BM Scorpii. This is a variable star which, with its intensity of light, also influences the change in the overall brightness of the star cluster. Charles Messier included this open set of stars in the catalog back in 1764, and it was also introduced as NGC6405.
