Messier 53 (M53 or NGC 5024) is a globular cluster in the constellation Coma Berenices.
The cluster displays various tidal-like features including clumps and ripples around the cluster, and tails along the cluster's orbit in an east-west direction.

NGC 5053 is a globular cluster with relatively low mass and low core concentration.

A tidal bridge-like structure appears to connect M53 with the close, very diffuse neighbor NGC 5053, as well as an envelope surrounding both clusters. These may indicate a dynamic tidal interaction has occurred between the two clusters; a possibly unique occurrence in the Milky Way since there are no known binary clusters within our galaxy.
