Sidereal astrology is a system of astrology that calculates the positions of the planets and zodiac signs based on the actual observable positions of the stars. It uses the sidereal zodiac, which aligns with the fixed positions of the constellations in the sky. This differs from tropical astrology, which is more commonly used in Western traditions and bases its zodiac on the seasons and the Earth's relationship to the Sun.
Our team works alongside Sidereal astrology with 13 signs as it incorporates the constellation Ophiuchus. Ophiuchus lies along the ecliptic (meaning as the Earth travels around the Sun, the Sun appears to pass in front of a succession of constellations. The linear path that the Sun describes across the sky is called the ecliptic). The constellations on the ecliptic path are collectively called the zodiac and extend a few degrees above and below the ecliptic line. This approach is not universally adopted but is a variation that some astrologers explore to align more closely with the astronomical reality of the sky.
