Introduction to Sidereal Astrology
Discover the astronomical truth behind your cosmic blueprint. Why the sky you see isn't the sky you've been told.
The Precision of the Stars
Most popular astrology uses the Tropical zodiac, which was fixed over 2,000 years ago. However, due to the precession of the equinoxes, the constellations have shifted by about 24 degrees in the sky.
Sidereal astrology accounts for this shift, aligning your birth chart with the actual, observable positions of the constellations at the exact moment of your birth.
Why It Matters
- Accuracy: Your signs align with the visible night sky.
- Depth: It taps into ancient systems of calculating planetary strength.
- Authenticity: You might discover you are a completely different sun sign!
