In typography, an asterism, ⁂, is a typographic symbol consisting of three asterisks placed in a triangle, which is used for a variety of purposes. The name originates from the astronomical term for a group of stars.^[1]

The asterism was originally used as a type of dinkus in typography, though increasingly rarely.^[2] It can also be used to mean "untitled" or author or title withheld – as seen, for example, in some editions of Album for the Young by composer Robert Schumann (№ 21, 26, and 30).^[3] In meteorology, an asterism in a station model indicates moderate snowfall.^[4][5]

A dinkus is a typographical device to divide text, such as at section breaks. Its purpose is to "indicate minor breaks in text",^[7] to call attention to a passage, or to separate sub-chapters in a book. An asterism used this way is thus a type of dinkus: nowadays this usage of the symbol is nearly obsolete.^[2] More commonly used dinkuses are three dots or three asterisks in a horizontal row.^[8][9] A small black and white drawing^{[10][full citation needed]} or a fleuron (❧)^[9] may be used for the same purpose. Otherwise, an extra space between paragraphs is used. A dinkus may be used in conjunction with the extra space to mark a smaller subdivision than a sub-chapter.
