What term describes a specific arrangement of stars forming a recognizable pattern?
Galaxy
Constellation
Planetarium
Star cluster
The correct answer is: Constellation
The correct term for a specific arrangement of stars forming a recognizable pattern is "constellation." Constellations are groups of stars that, when viewed from Earth, appear to form shapes or patterns often associated with mythological figures, animals, or objects. While they were historically used for navigation and seasonal change, constellations have also become significant in cultural and astronomical contexts; they help astronomers organize the night sky into manageable sections for studying celestial objects and phenomena. In contrast, a galaxy refers to a massive collection of stars, gas, dust, and dark matter bound together by gravity, while a planetarium is a venue that showcases astronomical displays, often using projectors to simulate the night sky. A star cluster is a group of stars that are physically close to each other in space, typically formed from the same molecular cloud, but does not necessarily imply a pattern recognizable from Earth as constellations do. Constellations are therefore distinct in the realm of astronomy for their unique arrangements and cultural significance.
