The scientific term for a grouping of stars is a "constellation." Constellations are patterns of stars that have been identified and named, often based on mythology, cultural significance, or the shapes they resemble. While the apparent proximity of stars in a constellation is purely a line-of-sight effect, these groupings help navigators and astronomers locate positions in the night sky. There are 88 officially recognized constellations in modern astronomy, each with its unique history and significance across different cultures and time periods.
