Asterism (typography)

In typography, an asterism ("group of stars")[1] is the typographic symbol consisting of three asterisks placed in a triangle: .

Now the symbol is used rarely and is nearly obsolete.[2] Its purpose is to "indicate minor breaks in text",[3] call attention to a passage, or to separate sub-chapters in a book.

Asterisms in use
Asterisms in James Joyce Ulysses, the "Wandering Rocks" chapter, from the 1922 edition. The 1961 edition used a hollow "white" star (☆), and the 1984 edition used a "dinkus" (***).

Often, this symbol is replaced with three consecutive asterisks (called a dinkus[4]), more than three asterisks, or three or more dots.[2] Otherwise, an extra space between paragraphs is used. An asterism or its analogue may be used in conjunction with the extra space to mark a smaller subdivision than a sub-chapter.

It can also be used to mean "untitled" or author or title withheld. For example, some editions of Album for the Young by composer Robert Schumann ( 21, 26, and 30).[5]

In meteorology, an asterism in a station model indicates moderate snowfall.[6][7]
