⛢

Etymology
A proposed alchemical symbol for platinum, derived from the symbols for the planetary metals gold $⟨☉⟩$ and iron $⟨♂⟩$, as platinum (previously known as 'white gold') was often found mixed with iron. This symbol for the newly discovered metal platinum was created in order to have a symbol to apply to the newly discovered planet Uranus.

Symbol

 * 1)  Uranus.
 * 2)  platinum.

Usage notes
While neither symbol is exclusive, $⟨⛢⟩$ is more common in astronomy and $⟨♅⟩$ in astrology. Use of either in astronomy is now uncommon.
