The zodiac signs are named after the constellations, but not tied to them. Even though Ophiuchus is undoubtedly an observed constellation , could it have the chance to be an actual member of the zodiac? Well, astronomers won’t comment on that part, considering astrology is not science, and astrologers aren’t buying that our signs have shifted. But in the "tropical zodiac", the system used by Western astrologers, there are fixed sectors of the sky through which the movement of the sun, moon and planets is tracked to create the basis for horoscopes. Astrologers say this shift in where the stars appear to be has no bearing on the "tropical zodiac" system. This is what is typically used for horoscopes in the West, and is based on segments of the sky calculated using the equinoxes on Earth.
