One of the many but overlooked open clusters in the constellation of Sagittarius is IC 4725 or, as it is more commonly known, M25. Recent studies have estimated this cluster to be only 90 million years-old, thus making it a very young cluster. The cluster lies approximately 2000 light-years away and its apparent diameter spans approximately one full moon at 32' and which translates to about 19 light-years across.
