Character entity reference: ☆
It is a special character which can sometimes be found in Japanese media. An example of this would be the manga らき☆すた (and the anime of the same name).
One reason for its appearance in Japanese media maybe be that it is readily available in Microsoft IME for Japanese. It can be accessed simply by typing "hosi" or "hoshi" (星) which is Japanese for star.
In Japanese it is often called 白星 (shiroboshi) which literally means "white star".
