What is a group of stars commonly referred to as?

A group of stars is commonly referred to as a constellation. Constellations are specific patterns formed by a relatively small number of stars, which are often used for navigation and storytelling in various cultures. These groupings of stars can be made up of stars at different distances from Earth, but they are perceived as a single shape or figure from our perspective.

While the other terms listed represent different astronomical concepts, they do not refer specifically to a group of stars in the same way. A galaxy is a much larger system that contains billions of stars, along with gas, dust, and dark matter. A cluster refers to a group of stars found within a galaxy. A solar system, on the other hand, consists of a star and the celestial bodies that orbit it, such as planets, moons, and asteroids. Therefore, constellation is the most accurate term for a recognizable group of stars.
