Asterism (astronomy)

Asterism refers to a prominent pattern or group of stars that can be recognized within a larger constellation. Unlike constellations, which have defined boundaries, asterisms can be simple shapes or familiar formations that are visible in the night sky. For instance, the Big Dipper is an asterism within the larger constellation of Ursa Major. Asterisms help stargazers navigate the sky and are significant in mythology and culture, often serving as reference points or guides for identifying other celestial objects.
