The presence of Ophiuchus on the ecliptic circle is a well-known fact. It's located between Sagittarius and Scorpio, and, according to the established opinion, is either completely or partially absorbed by Scorpio constellation. However, if you look closely at the map of the celestial sphere, you may be surprised to find that Ophiuchus covers the ecliptic much more than Scorpio. This means that the Sun stays in this constellation for a long time - in fact, 18 days a year. And, given the astrological principle that the energy of the constellations affects the inhabitants of the Earth, we can conclude that Ophiuchus persons are born much more often than Scorpios ones. But how can we adapt the astrological knowledge accumulated over the centuries to interpret the new constellation of the Zodiac? Maybe we can fill in the missing gaps with the help of Ophiuchus? Let's figure it out.
Everyone knows about classical astrology of 12 zodiac signs because media made it very popular. Someone have heard of vedic astrology, which is based on Indian philosophy; It's actively used by people who are fond of yoga. But few people know about the sidereal astrological system, which is based on real astronomical data. Studying and practicing astrology, I became an adherent of the sidereal approach - its results impressed me very much. To show you visual differences between the tropical, vedic and sidereal systems, I made an infographic.
