Affliction

Planetary States

A condition where a planet is under stress, usually due to difficult aspects (like squares or oppositions) from malefic planets (Mars, Saturn) or being in a difficult house.

Deep Dive:An afflicted planet may struggle to express its positive qualities, often manifesting as challenges or obstacles in the areas of life it rules.

Air Signs

Signs & Houses

Deep Dive:People with dominant Air placements are often thinkers, communicators, and social connectors. They value logic, ideas, and objectivity.

Angular Houses

Signs & Houses

The 1st, 4th, 7th, and 10th houses of a chart. These are considered the most powerful houses where planetary energy manifests most visibly.

Deep Dive:Planets in angular houses have "accidental dignity" and are capable of producing significant effects in the native's life.

Applying Aspect

Aspects

An aspect where the faster-moving planet is approaching the exact degree of the aspect with a slower planet.

Deep Dive:Applying aspects are considered stronger and more event-oriented than separating aspects, as the energy is building up towards a peak.

Ascendant (Rising Sign)

Signs & Houses

The zodiac sign that was rising on the eastern horizon at the exact time and place of birth. It represents the persona, physical body, and first impressions.

Deep Dive:The Ascendant sets the structure for the entire house system. It is often described as the "mask" one wears or the lens through which one views the world.

Aspect

Aspects

The geometric angle formed between two planets or points in a birth chart (e.g., 0°, 60°, 90°, 120°, 180°).

Deep Dive:Aspects describe the dynamic relationship between planetary energies. "Soft" aspects (trine, sextile) facilitate flow, while "hard" aspects (square, opposition) create tension and growth.

Small celestial bodies used in modern astrology to add nuance to chart interpretation. Major asteroids include Chiron, Ceres, Pallas, Juno, and Vesta.

Astrology
