names = UGC 9792, GCl 32Palomar 5 is a
globular cluster discovered byWalter Baade in 1950. It was independently found again byAlbert George Wilson in 1955. After the initial name of Serpens, it was subsequently cataloged 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 astellar stream . The stream has a mass of 5000 solar masses and is 30,000 light years long.
