Messier 67 (2019)

Messier 67 is an open cluster located in the constellation of Cancer. It is one of the older closest open clusters at an estimated age of 3.2 to 5 billion years. Most clusters tend to disperse after their formation, but M67 is expected to stay together for another 5 billion years. It contains at least 500 members and has undergone mass segregation where the more massive stars have migrated towards the center of the cluster.
