Pluto's bident, stylized like Neptune's trident and surmounted by a globe or cap. Popularized by Paul Clancy, founder in 1933 of American Astrology magazine.[1]

⯓

1. (astrology) Pluto.
2. (astronomy, rare) Pluto as a dwarf planet.

⟨⯓⟩ is the most common astrological symbol for Pluto in English-language sources, and perhaps globally.[1] It was originally an exclusively astrological symbol, with only ⟨♇⟩ being used in astronomy (though often ⟨♇⟩ was found in astrology as well). However, since the 2006 reclassification of Pluto as a dwarf planet, ⟨⯓⟩ has seen some use in astronomical sources.[2]
