M11 got its nickname, the Wild Duck Cluster, from Admiral Smyth. His view in 1835 seemed to elicit visions of wild ducks flying in the distant sky. With the growth of large cities, seeing similar flocks fill the sky are most rare indeed.

Description
English: M11 got its nickname, the Wild Duck Cluster, from Admiral Smyth. His view in 1835 seemed to elicit visions of wild ducks flying in the distant sky. With the growth of large cities, seeing similar flocks fill the sky are most rare indeed. This is certainly one of the more compact examples of open star clusters with members numbering nearly 3000 stars. The oldest stars in this cluster are only 220 million years old, indicating that this cluster is still quite young. But the true vision of wild ducks can be better glimpsed by our understanding of these starsʼ orbits. A picture like this is only a snapshot of the convoluted and complex orbital interactions these stars dance through time. Each star affects the other in their messy mingle about each other; as ducks they would appear to be very confused. A stargazer on a planet orbiting one of these stars would see a sky filled with hundreds of nearly identical first magnitude stars.
