What are aspects and why do they matter?

Aspects are geometric angles between planets in your chart. Major aspects include: Conjunction (0°) - blended energies, Sextile (60°) - opportunities, Square (90°) - tension and growth, Trine (120°) - natural flow, Opposition (180°) - awareness through polarity. Aspects show how your planetary energies interact, creating your unique personality dynamics. Challenging aspects (squares, oppositions) often drive growth, while harmonious aspects (trines, sextiles) show natural talents.
