two types of star clusters are Open clusters and globular clusters
A group of stars that are closer together than the surrounding stars is called a star cluster. Star clusters can be divided into two main types: open clusters and globular clusters, with open clusters being more loosely bound than globular clusters.
Open clusters lie along the Milky Way and half of the globular clusters are in or near the constellation Sagittarius.
Open clusters are loosely bound groups of young stars that are found in the disk of a galaxy, while globular clusters are tightly packed groups of old stars that are found in the halo of a galaxy. Open clusters have fewer stars and are more spread out, while globular clusters have many more stars and are more densely packed. In terms of composition, open clusters contain mostly young, hot stars with higher metal content, while globular clusters contain mostly old, cool stars with lower metal content.
Any major galaxy has LOTS of star clusters, including globular clusters, if that's what you mean.
Constellation or "asterism". The difference is that "constellations" are officially recognized by the International Astronomical Union, while an "asterism" is any other pattern or grouping of stars.
a globular cluster
A huge star group that rotates around a common center is called a star cluster. Star clusters can be classified into two main types: globular clusters, which are tightly packed groups of stars, and open clusters, which are looser groupings of stars.
Those are called globular clusters, or star clusters.
Globular star clusters are members of the Milky Way galaxy. They are dense, spherical collections of stars that orbit the galactic center. These clusters contain thousands to millions of ancient stars and are typically found in the galactic halo.
A misty group of stars is referred to as a star cluster. Star clusters are groups of stars that are gravitationally bound together and can be classified as either open clusters (loose grouping of stars) or globular clusters (more densely packed grouping of stars).
There are two types of star clusters. Globular clusters are tight groups of hundreds of thousands of very old stars which are gravitationally bound, while open clusters, are more loosely clustered, generally containing less than a few hundred stars, and are usually very young.
