The Wild Duck Cluster (also known as NGC 6705) is an open cluster in the constellation Scutum.
The Wild Duck Cluster is one of the richest and most compact of the known open clusters, containing about 2900 stars of which 500 are bright enough to make it fun to see. It is about 6,000 light years away. 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 ducks. This flock was likely easier to see when fewer background stars were visible to an observer (as in the early days of telescopes).
