This wheel shows your natal chart - the position of planets at the time of your birth. The chart is divided into 12 houses, each representing different areas of life.
| Planet | Sign | Degree | House | Motion |
|---|
The Ascendant (rising sign) represents your outward personality, while the Midheaven (MC) relates to your public life and career.
The North Node (Rahu) represents your soul's growth direction in this lifetime, while the South Node (Ketu) represents past life abilities.
| House | Sign | Degree | Life Area |

This chart uses the Placidus house system, one of the most commonly used systems in Western astrology.
House systems divide the ecliptic into 12 segments that represent different areas of life. The Placidus system is time-based, dividing the ecliptic based on the diurnal motion of the celestial bodies.

The transit chart compares your natal positions with current planetary positions, showing how current celestial energies may be influencing your birth chart.
Synastry is the comparison of two birth charts to understand relationship dynamics. In this chart, planets from each person are overlaid on the same wheel to reveal how they interact with each other.
The inner wheel (blue symbols) shows Person 1's planets, while the outer wheel (red symbols) shows Person 2's planets. Lines between planets represent aspects (connections) that reveal compatibility, challenges, and potentials.

Synastry is the study of how two people's charts interact. The aspects (angular relationships) between planets in different charts reveal compatibility, challenges, and growth potential.
The composite chart represents the relationship itself as a separate entity. It's created by finding the mathematical midpoint between the same planets in two individual birth charts.
This chart reveals the shared purpose and inherent nature of your relationship, showing the unique energy you create together. Think of it as the "third entity" that emerges when two people connect.
| Planet | Sign | Degree | House |

Composite planets represent the mathematical midpoint between the same planet in two individual charts. They show the core energy of the relationship itself, rather than how individuals interact.
| House | Sign | Degree |
|---|
Composite houses reveal the relationship's focus and how its energy is distributed across different life areas.
Composite aspects reveal the inherent patterns and energies within the relationship itself, showing key themes and dynamics.
| Planets | Aspect | Orb | Meaning |
|---|
The composite chart represents the midpoint between two people's charts, showing the relationship as its own entity with its own purpose. These aspects reveal the inherent nature and dynamics of the relationship itself, beyond how the individuals interact.
Transit aspects show how current planetary positions are interacting with your natal chart. They indicate current energies, challenges, and opportunities.
| Aspect | Natal Position | Transit Position | Orb | Impact |
|---|
Transit aspects indicate how current planetary positions are influencing your natal chart. High impact aspects with small orbs (less than 1°) are more potent. Consider the houses involved for specific life areas being affected.
Synastry aspects show how planets in two birth charts interact with each other, revealing relationship dynamics, challenges, and natural harmony.
| Aspect | Person 1 | Person 2 | Orb | Impact |
|---|
Synastry aspects reveal how two people naturally interact. Harmonious aspects (conjunctions, trines, sextiles) show ease and flow, while challenging aspects (squares, oppositions) can indicate growth areas that may require effort to navigate.

Your natal chart is a map of the sky at the exact moment you were born. It reveals your personality traits, potential challenges, and natural talents.
The positions of planets in various signs and houses paint a complete picture of your core essence and life path.
Transit charts compare your natal chart with the current positions of planets, showing how today's cosmic energies are affecting you personally.
Pay special attention to transits involving your Sun, Moon, Ascendant, and any natal planets in challenging aspects.
Synastry charts compare two individual birth charts to reveal the dynamics between two people. They show how your planets interact with each other, highlighting areas of harmony and potential tension.

The composite chart represents the relationship itself as a unique entity. It's created by finding the mathematical midpoint between the same planets in two different charts.
While synastry shows how two people interact with each other, the composite chart reveals the purpose and nature of the relationship as its own being.
