Core Definitions
-
Ingress
When a planet moves into a new zodiac sign. Ingresses mark shifts in collective energy and set the tone for how that planet expresses itself.
-
Retrograde
The apparent backward motion of a planet from Earth’s perspective. Retrogrades often symbolize review, reflection, delays, or revisiting past themes.
-
Direct
When a planet resumes forward motion after a retrograde. Direct stations signal clarity, progress, and forward movement in the areas that the planet governs.
-
Lunation
A collective term for moon phases (New Moon, First Quarter, Full Moon, Last Quarter). Lunations highlight cycles of beginnings, growth, culmination, and release.
-
Eclipse
Special lunations (solar or lunar) where the Sun, Moon, and Earth align. Eclipses are powerful catalysts for change, often bringing fated events, revelations, or endings.
Asteroids & Centaurs
-
Vesta
The spark of life that helps us understand how we feel about our home, family, and ourselves. Symbolizes devotion, sacred focus, and the hearth flame. In charts, Vesta highlights where we dedicate ourselves with purity and service.
-
Ceres
Associated with nurturing, cycles of loss and renewal, and the mother archetype. Ceres speaks to how we care for others and ourselves. She’s a dwarf planet between Mars and Jupiter and is associated with fertility and agriculture.
-
Juno
Represents marriage, partnership, commitment, and contracts. Juno’s placement shows what we seek in unions and how we approach loyalty.
-
Pallas (Pallas Athena)
Embodies wisdom, creative intelligence, and strategy. Pallas reflects problem‑solving, pattern recognition, and artistic vision. Pallas is connected to the use of the left side of our brain.
-
Chiron
Known as the “Wounded Healer.” Chiron points to deep vulnerabilities and the potential for healing, teaching, and transformation through those wounds.
-
Chariklo
Chariklo represents grace, boundaries, and the quiet magic of being held. She teaches that healing doesn’t require force — only presence. Her energy mirrors her celestial rings: soft, protective, and intentional. Wherever Chariklo touches your chart, you’re learning to create spaces where truth can soften, trust can grow, and transformation can unfold at its own pace.
Planetary Aspects
-
Conjunction
Two planets sitting together, blending their voices. A conjunction feels like a merging — not good or bad, just intense. It’s a moment where energies fuse, amplify, and ask to be witnessed. Think of it as two parts of yourself speaking at the same time, inviting integration rather than urgency.
-
Sextile
A gentle opportunity, soft and supportive. Sextiles open doors without forcing you to walk through them. They’re the “if you feel ready” aspects — encouraging, spacious, and aligned with nervous‑system safety. You can lean in or simply notice.
-
Trine
Ease, flow, and natural harmony. Trines feel like exhaling. They highlight what already works, what already feels good, and what your body naturally knows how to do. They’re not about productivity — they’re about remembering your innate gifts.
-
Square
Tension that wants movement, not perfection. Squares aren’t conflict; they’re friction that creates growth. They show where something is rubbing up against your edges, asking for adjustment, boundaries, or a new way of relating. They’re invitations to shift, not crises.
-
Opposition
A mirror moment — seeing two truths at once. Oppositions illuminate polarity: self vs. other, rest vs. action, inner world vs. outer world. They’re not about choosing sides. They’re about finding the middle path that honors both needs without abandoning yourself.
-
Quincunx (Inconjunct)
A subtle misalignment that asks for recalibration. This aspect feels like something is “almost but not quite” fitting. It’s not a problem — it’s a nudge to adjust, refine, or shift perspective. Gentle curiosity works better than force here.
-
Stellium
A cluster of planets focusing energy in one area. A stellium concentrates attention, emotion, and growth in a single part of your life. It’s not intensity for intensity’s sake — it’s a season of deepening, where your soul is doing important work.
