Why does Jupiter have the symbol it does?

Jupiter's symbol (♃) is derived from the astrological and alchemical traditions, representing the Roman god Jupiter, the king of the gods. The symbol consists of a stylized representation of a lightning bolt and a cross, reflecting Jupiter's association with thunder and authority. This symbol has been used in astronomy and Astrology to denote the planet and its influences, embodying its characteristics of expansion, growth, and luck.
