Messier 52 (also known as M 52 or NGC7654) is an open cluster in the Cassiopeia constellation. It was discovered by Charles Messier in 1774. M52 can be seen from Earth with binoculars. Due to interstellar absorption of light, the distance to M 52 is uncertain, with estimates ranging between 3,000 and 7,000 light years. One study identified 193 probable members of the cluster, with the brightest member being magnitude 11. Messier 52 is evaluated at about 35 million years old. It can be seen against the backdrop of a Milky Way field. This object has been described as a "salt and pepper" cluster due to its dense arrangement of about 200 bright stars. M52 is believed to be only 23 million years old. Its distance from Earth is not certain. Estimates range anywhere from 3,000 to 7,000 light-years. With a magnitude of 7.3, this cluster is easily visible to an observer with binoculars. A small telescope will reveal the cluster's fainter stars.
