Palomar 5

Palomar 5 is a globular cluster in the constellation Serpens and a member of the Palomar Globular Clusters group. It was discovered by Walter Baade in 1950, and independently found again by Albert [George Wilson] in 1955. After the initial name of Serpens, it was subsequently catalogued as Palomar 5.
There is a process of disruption acting on this cluster because of the gravitation of the Milky Way – in fact there are many stars leaving this cluster in the form of a stellar stream. The stream has a mass of 5000 solar masses and is 30,000 light years long. The cluster is currently from the Galactic Center. It shows a noticeable amount of flattening, with an aspect ratio of between its semimajor axis and semiminor axis.
