Asteroid 6630 Skepticus was discovered on November 15, 1982 at the Anderson Mesa unit of Lowell Observatory in Flagstaff, Arizona by Edward Bowell. Skepticus has a period of 3 years, 124 days.
It was named for the Committee for the Scientific Investigation of Claims of the Paranormal (CSICOP) on the twentieth anniversary of its founding. CSICOP (pronounced Sigh-cop) is a nonprofit education organization, established in 1976 to investigate paranormal, occult, and fringe claims; articles and reports of its studies are published in its journal The Skeptical Inquirer.
The word skepticism comes from the Latin word scepticus(pronounced "skepticus"), which is derived from the Greek word for thoughtful, skeptikos. The Greek verb skeptesthai means "to look" or "to consider."
The dictionary defines skepticism as (1)an attitude of doubt or a disposition to incredulity in general or toward a particular object,(2)the doctrine that true knowledge or knowledge in a particular area is uncertain, (3)the method of suspended judgment, systematic doubt, or criticism characteristic of skeptics, or (4) doubt concerning basic religious principles. And this is what the influence of asteroid Skepticus is all about.
Michael Jackson and philosopher and freethinking writer Ayn Rand both have Skepticus prominent in their charts: Jackson has it conjunct his Mercury(the media, young people) as well as his Fortuna in the tenth house of reputation, and Rand had Skepticus conjunct her Uranus(and Symmetria and Pia), symbolizing her fierce, rigid public devotion to reason. Ken Kesey, novelist and famed 1960s counterculture figure who wrote One Flew Over The Cuckoo's Nest, had Skepticus conjunct the East Point in the first house.
The glyph for Skepticus is my own conception.
