This character is a Other Symbol and is commonly used, that is, in no specific script. The character is also known as alchemical symbol for purify.
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+260B forms with similar adjacent characters prevents a line break inside it.
The Wikipedia has the following information about this codepoint:
An orbital node is either of the two points where an orbit intersects a plane of reference to which it is inclined. A non-inclined orbit, which is contained in the reference plane, has no nodes.
