Beehive Cluster

Designation: M44 / NGC 2632
Hemisphere: Northern
Constellation: Cancer
Distance: 610 light years
Object type: Open Cluster


The Beehive Cluster is a bright, large open cluster (a group of stars formed from the same cloud of gas and dust) in the constellation of Cancer, the Crab. Also known as Praesepe (Latin for “manger”), M44 lies roughly 610 light years away, which makes it one of the nearest open clusters to Earth, and it spans some 15 light-years.

Visible to the naked eye, the Beehive Cluster contains around 1,000 stars, more than most nearby bright open clusters. These are fairly young stars at approximately 600 million years old (by comparison our Sun is 4.5 billion years old). The Beehive Cluster and the nearby Hyades Cluster have similar age and motion and it is therefore believed that the two clusters may have formed together from the same molecular cloud.
