The Wild Duck Cluster (also known as Messier 11, or NGC 6705) is an w:open cluster in the w:constellation w:Scutum. It was discovered by w:Gottfried Kirch in 1681. w:Charles Messier included it in his catalogue in 1764.

The Wild Duck Cluster is one of the richest and most compact of the known open clusters, containing about 2900 w:stars. Its age has been estimated to about 220 million years. Its name derives from the brighter stars forming a triangle which could represent a flying flock of w:ducks.
