2 | If someone told you that the FBI deemed your sign "dangerous," don't believe them.

In 2018, USA Today debunked a report that was making the rounds on the internet. This ranking of the "most dangerous signs" purported to be sourced from the Federal Bureau of Investigation (FBI), but the agency denies doing any kind of astrological analysis of the criminals it investigates. Whoever generated the false report, though, was clearly distrustful of Cancers.

3 | The oldest horoscope we know of is from 410 B.C.

Humans have been trying to get insight into their lives based on the stars for thousands of years. According to an article on Babylonian horoscopes published in the Journal of Cuneiform Studies, the oldest horoscope that has been discovered was for Apr. 29, 410, B.C. and was written in cuneiform.

5 | In Japan, you may be asked for your blood type instead of your sign.

Blood type personality, or ketsueki-gata, is a Japanese belief that it's one's blood type that may determine aspects of their personality. According to Very Well Health, the pseudoscience can be traced back to 1930 when a professor named Tokeji Furukawa suggested the possibility that there could be a correlation between blood types and certain traits. People with A blood are thought to be creative and stubborn, for example, while those with O are confident and self-centered.

While it's become incredibly common and is not considered as serious a sin now, one prominent Catholic, mathematician Aquila Ponticus, was excommunicated from the church in 120 A.D. for practicing astrology.

14 | The origins of astrology go way back in history.

“We don’t really know who first came up with the idea for looking at things in nature and divining influences on humans,” NASA astronomer Sten Odenwald told Time. “There’s some indication that cave art shows this idea that animals and things can be imbued with some kind of spirit form that then has an influence on you, and if you appease that spirit form, then you will have a successful hunt. That was taken over by the idea of divination, where you can actually look at things in nature and study them carefully, such as tea-leaf reading.”

15 | An astrologer seemingly predicted an attempt on Hitler's life.

21 | We almost had a 13th sign.

29 | The dreaded Mercury retrograde happens three or four times annually.
