Alternative forms

Is astrology and alchemy (gold), a variant with a face: 🌞︎ is sometimes seen. This does not occur in astronomy, botany or (obsolete) chemistry.

Etymology

The shield of the sun god Apollo, with a boss in the center. Medieval replacement of ⟨🜚⟩, the sun with a single ray, which in ancient times had replaced a sun orb surrounded by multiple rays.

Compare the Egyptian hieroglyph ⟨⟩ and the Chinese character ⟨⟩, both of which mean 'sun' and 'day'.
