Where it comes from

From Ancient Greek ἀστερισμός (asterismós, “a group of stars”), from ἀστήρ (astḗr, “star”). Analyzable as aster- + -ism.

noun asterisms

  1. An unofficial constellation (small group of stars that forms a visible pattern). The Big Dipper, Summer Triangle, and Orion's Belt are asterisms.
  2. A rarely used typographical symbol of three asterisks arranged in a triangle, ⁂, used to call attention to a passage or to separate subchapters in a book. Distinct from a dinkus which also uses asterisks to separate.
  3. A star-shaped figure exhibited by some crystals by reflected light (as in a star sapphire) or by transmitted light (as in some mica).
