Everything you need to understand your True Stars chart — from the real sky to the soul stats that make you, you.
The Real Sky: A 2,000-Year Restoration
True Stars does not show you where an ancient calendar says the planets should be. It shows you where they actually were among the stars at the exact minute of your arrival. If you had looked through a telescope at the moment of your birth, this is precisely what you would have seen.
The Great Disconnect: Why Tradition Stalled
Most Western astrology relies on the Tropical Zodiac, a geometric system frozen in time nearly 2,000 years ago. Around 150 AD, the astronomer Claudius Ptolemy published the Tetrabiblos. Ptolemy tied the zodiac to the seasons instead of the stars, anchoring 0° Aries to the March Equinox. At the time, the equinox and the constellation roughly overlapped.
However, Ptolemy was aware of precession—the slow, 26,000-year wobble of Earth's axis—but he chose to ignore it. He "paused" the zodiac, locking it to the calendar and letting the actual stars drift away.
The 24-Degree Reality Gap
Over the last 2,000 years, that "drift" has shifted the tropical frame roughly 24 degrees away from the physical constellations. When a tropical chart claims your Sun is in Aries, the Sun was physically in Pisces that day. Standard horoscope apps are still based on this Roman-era frozen snapshot—a map that hasn't matched the sky since the fall of the Empire.
Pure Observational Astronomy: Beyond the Ayanamsha
While Vedic (Jyotish) astrology uses a correction called an Ayanamsha (like Lahiri) to account for this drift, True Stars goes a step further. We have removed the mathematical "middlemen" entirely. Instead of dividing the sky into twelve equal 30° boxes, we use the IAU Constellation Boundaries—the official, physical borders recognized by the International Astronomical Union since 1930.
Nature is not symmetrical. On our map, Virgo spans a massive 44 days, while Scorpio is a tiny 7-day sliver.
The Inclusion of the 13th Sign
Because we use the actual path of the Sun (the ecliptic), we include the 13th constellation: Ophiuchus, the Serpent-Bearer. Sitting between Scorpio and Sagittarius, Ophiuchus is a physical astronomical reality that tropical astrology has quietly ignored for centuries to maintain 12-sign symmetry.
High-Precision Data: Our Technical Standards
To ensure our charts are unassailable, we utilize NASA-grade data and advanced astronomical algorithms:
- Swiss Ephemeris (JPL DE431): We pull planetary positions from the same high-precision NASA JPL data used by major observatories, compressed into the Swiss Ephemeris library.
- Topocentric Reality: Unlike standard charts calculated from the Earth's center, we use your literal latitude and longitude to account for Parallax Error.
- Yoga Tara Point-Mapping: We've replaced "equal boxes" for the 27 Nakshatras with actual star coordinates from the Yale Bright Star Catalog, precessed to your birth epoch.
- Ecliptic Projection: We account for planets floating "above" or "below" the 13-sign belt by projecting their position straight down onto the ecliptic path (longitude).
- Physical Perigee: We report the planet's literal distance from Earth (AU) alongside retrograde status, replacing symbolic motion with physical proximity.
Why This Matters
The ancient traditions behind signs like Virgo were inspired by the visible stars long before they were forced into 30° geometry. By returning to the True Sky, we aren't changing the soul of astrology; we are simply restoring its eyes.
Your chart should reflect the universe as it actually was, not as a Roman-era astronomer decided it should be forever.

These are the 13 constellations the Sun actually passes through. Unlike the tropical zodiac's equal 30-degree signs, these are the real star groups — each with its own size and character.

The Houses
12 areas of life in your chart
Houses divide your chart into 12 areas of life using the Porphyry system, where the Ascendant and Midheaven define the four angles and the intermediate cusps are calculated by trisecting each quadrant. Planets in a house bring their energy into that area of your life.

The Nakshatras
27 lunar mansions
The 27 nakshatras are lunar mansions — ancient star-based divisions that give far more detail than constellations alone. Each spans 13.33 degrees and has its own ruling planet, symbol, and spirit animal. Your Moon's nakshatra is especially important in Vedic astrology.
Soul Stats

Soul Stats
Goal, Nature, Mind, and Body
Each nakshatra carries four qualities that describe its deeper nature. Together, these Soul Stats paint a picture of what drives you, how you relate to others, how your mind works, and how your body operates.
Goal (Purushartha)
The four aims of human life in Vedic philosophy. Your nakshatra's purushartha reveals your soul's primary motivation.
Nature (Gana)
Three temperament types that describe how you interact with the world around you.
Mind (Guna)
Three fundamental qualities of consciousness that shape how your mind operates.
Body (Dosha)
Three Ayurvedic body types that describe your physical constitution and health tendencies.

Aspects are geometric relationships between planets based on the angular distance between them. When two planets form an aspect, their energies interact — sometimes harmoniously, sometimes with tension.

Transits are the current positions of planets in the sky compared to where they were when you were born. They show how today's cosmic weather affects your personal chart — like a weather report for your life.
