Vulcano is asteroid #4464, also known as 1966 TE, and a member of the Hungaria-family within the Hungaria-group in the Inner Asteroid Main Belt. Vulcano was discovered by Nikolai Stepanovich Chernykh (Николай Степанович Черных) and named after one of the Aeolian Islands. It is indeed named Vulcano and a small volcanic island roughly 25 km north of Sicily. The word volcano and its counterparts in many other languages were all originally derived from the name of this small island.

Vulcanus is an invented planet of the Uranian school of astrology. This Vulcanus hints to peaks in power, force, or energy.

Martha Lang-Wescott describes the meaning of the invented Uranian Vulcanus as awareness of invisible power, the power of influence, feeling forced to associate, compulsion, a surge of strength. An asteroid with the name Vulcanus doesn’t exist because this name is reserved for a celestial object with an orbit closer to the Sun than Mercury’s. But astronomers are already sure that such a celestial object doesn’t exist at all. Hence the name Vulcanus will never become an official name of any celestial body within the Solar System, while the term vulcanoids denotes celestial objects, which cross the orbit of Mercury. As far as currently known are only Phaethon and Icarus doing this. Hence Martha Lang-Wescott abuses the asteroid Volcano to represent the same meanings as Vulcanus too. I must wonder why she needs so desperately an asteroid to represent these meanings when she already uses the invented Uranian planet.

Volcano is in truth of course a place name asteroid, hence representing a certain place. Because other volcanoes got their name also from this specific place, so Volcano can represent all volcanoes. But you won’t be able to predict volcanic eruptions with the help of this asteroid. Research in the forecasting of disasters has already revealed that the cause of a disaster is of minor relevance in any astrological chart related with disasters. Of relevance is instead the loss due to the disaster, especially the loss of human lives. Maybe you could forecast harmless sightseeing on a volcano with the help of this asteroid. But it certainly hasn’t more relevance than this.
