If there’s no article about it in The New York Times, then I wouldn’t worry about it. Also the Minnesota Planetarium Society is pretty much the only organization that supports changing the astrological signs. Therefore, I declare the claim that I am not a Gemini is false.

There are essentially no respected authorities that can validate the claims of the Minnesota Planetarium Society. The only articles I can find are about the fact that the Society has implemented their own new Zodiac assignments. The sources that support this change are mostly blogs and tabloids with little to no credibility.
