M44 is an open cluster of stars in the constellation Cancer. M44 is one of the nearest open star clusters to us, and is visible to the naked eye. As a result, the star cluster was known to the ancients as the Praesepe (which is a Latin translation of the ancient Greek name Phatne). To the naked eye, M44 looks like a hazy patch in the sky. When Galileo turned a telescope toward the heavens in the early 1600's, he was the first to realize that the Praesepe was a cluster of stars. Another popular name for M44 is the Beehive star cluster. The Hipparcos satellite determined that this star cluster is 577 light-years away. M44 is estimated to be about 600 to 730 million years old.
The constellation Cancer has two objects that are listed in the Messier Catalog. In addition to M44, Cancer also includes the M67 star cluster.
