What is the closest open cluster to Earth?

The Hyades is recognized as the closest open cluster to Earth and is located about 153 light-years away in the constellation Taurus. Open clusters are groups of stars that are physically related and formed from the same molecular cloud. The stars in the Hyades cluster share a common origin and are relatively young compared to other stellar formations.

The proximity of the Hyades makes it a significant point of interest for astronomers studying the evolution of stars and their interactions within clusters. It also serves as a useful reference point for measuring distances to other astronomical objects due to its well-defined location and the relative brightness of its member stars.
