U+2BE6 "⯦" Vulcanus Unicode Character

U+2BE6 "⯦" Vulcanus is a symbol included in the Miscellaneous Symbols and Arrows block, used primarily in astronomy and astrology to represent the hypothetical planet Vulcan, which was once theorized to exist within the orbit of Mercury to explain anomalies in Mercury's perihelion precession before Einstein's general relativity provided a more accurate model. The symbol itself resembles a small circle bisected by a vertical line, a variation of the classical planetary cross and circle motif, and it carries historical significance as a relic of 19th-century celestial mechanics and the search for missing planets within the solar system.
