Star Groups are collections of stars that are bound together by gravity. These groups can vary in size and can include a few stars or thousands of them. Some well-known examples of star groups are star clusters and galaxies. They help astronomers study the formation and evolution of stars in the universe. Within these star groups, stars often share similar characteristics, such as age and chemical composition. This makes them valuable for research, as scientists can learn about the life cycles of stars and how they interact with one another. Understanding star groups also helps us comprehend the larger structure of the universe.
