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]

Asterisms in use
Asterisms used as dinkuses in the James Joyce novel Ulysses, the "Wandering Rocks" chapter, from the 1922 edition.[2] The 1961 edition used a hollow white star (☆), and the 1984 edition used a row of three asterisks.

The asterism was originally used as a type of dinkus in typography, though increasingly rarely.[3]

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).[4]

In meteorology, an asterism in a station model indicates moderate snowfall.[5][6]


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.[3] 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.
