This character is a Math Symbol and is commonly used, that is, in no specific script.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+22C6 forms with similar adjacent characters prevents a line break inside it. The glyph can be confused with one other glyph.
The CLDR project calls this character “star operator” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: operator, star.
The Wikipedia has the following information about this codepoint:
In typography, a star is any of several glyphs with a number of points arrayed within an imaginary circle. A commonly used star symbol is the asterisk.
