An asterisk (*) is a typographical symbol or glyph. It is so called because it resembles a conventional image of a star (Latin astrum). Computer scientists often pronounce it as star (as, for example, in the A* algorithm).

The asterisk derives from the need of the printers of family trees in feudal times for a symbol to indicate date of birth. The original shape was six-armed, each arm like a teardrop shooting from the center. For this reason, in some computer circles it is called a splat, perhaps due to the "squashed-bug" appearance of the asterisk on many early line printers.

In this form the character appeared in typewriters. However, some typewriters had difficulty printing the six arms distinctly. Furthermore, due to Arab-Israeli tension, many Arabs would not buy typewriters with a six-armed symbol, which they identified with the Star of David on the Israeli flag. Hence many systems use a distinct symbol referred to as the "Arabic star", and given a distinct character in Unicode, U+066D and the official name "Arabic five-pointed star".

In some fonts, however, the asterisk is five-pointed and the Arabic star is eight-pointed. The two symbols are compared below (the display depends on your browser's font).
