Five-pointed star

A five-pointed star (☆) is a common ideogram used throughout the world. If the colinear edges are joined together a pentagram is produced.

The five-pointed star, geometrically a regular concave decagon, used in flags originates from European or Western heraldry, and the golden five-pointed star has associations with military power and war. It has also become a symbol of fame or "stardom" in Western culture.
