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. Based on measurements of the stars from the Gaia spacecraft, it is at least 65,000 light-years (20,000 parsecs) from the Sun.

This star cluster is further away than the SagDEG satellite galaxy.

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.
