Messier 67 Open Star Cluster
Messier 67 (M67), also known as NGC 2682, is an open star cluster located in the constellation of Cancer. This cluster is particularly interesting because it is one of the oldest open clusters known, with an estimated age of about 3.2 to 4.8 billion years. It contains roughly 500 stars, including several red giants, white dwarfs, and sun-like stars. M67 is a rich cluster and has been extensively studied, especially because its stars share a similar age and chemical composition, providing valuable insights into stellar evolution.
