asterism

Stars forming shapes

An asterism is a pattern of stars that forms a recognizable shape but isn't officially one of the 88 constellations—the Big Dipper is an asterism within the constellation Ursa Major.

In typography, an asterism is a triangular cluster of three asterisks (⁂) used to mark a section break or call attention to a passage.

In gemology, an asterism is the star-shaped pattern of reflected light seen in certain polished stones like star sapphires.
