what is the closest open cluster to our solar system
An open cluster, also known as galactic cluster, is a group of up to a few thousand stars that were formed from the same giant molecular cloud and have roughly the same age.he nearest open cluster is the Hyades: the stellar association consisting of most of the Plough stars is at about half the distance of the Hyades, but is a stellar association rather than an open cluster as the stars are not gravitationally bound to each other.
Astronomers were using the European Southern Observatory's Very Large Telescope Survey Telescope (VST) in Chile to study the largest star cluster in the Milky Way galaxy, a collection of several hundred thousand stars about 16,000 light-years from Earth known as Westerlund 1.
