Palomar 4 is a globular cluster of the Milky Way galaxy. It was discovered in 1949 by Edwin Hubble and again in 1955 by A. G. Wilson. It is 356,000 light-years away.
This star cluster is further away than the Magellanic Clouds and SagDEG satellite galaxies.
Initially it was thought to be a dwarf galaxy, and it was given the name Ursa Major Dwarf. However, it was later discovered to be a globular cluster.
