    The Big Three

    Sun, Moon, and Rising together form the foundation of your chart. Most people only know their Sun sign — your full picture is far richer.

    Sun Sign

    Core identity, vital drive, and your conscious life purpose. The sign the Sun occupied at your birth.

    Moon Sign

    Emotional needs, instinctive reactions, and your private inner self. Changes sign every ~2.5 days.

    Rising Sign

    Your Ascendant — the outer persona, physical energy, and how the world first perceives you.

    Frequently asked questions

    What is a Western birth chart (natal chart)?+

    A natal chart is a snapshot of the sky at the exact moment and location of your birth, calculated using the tropical zodiac. It maps the Sun, Moon, and 8 planets across 12 houses and shows the angular relationships (aspects) between them. It's the foundation of all Western astrological analysis.

    What is the difference between Sun sign, Moon sign, and Rising sign?+

    Your Sun sign (zodiac sign) shows your core identity and life purpose. Your Moon sign reveals your emotional nature, instincts, and inner world. Your Rising sign (Ascendant) is the sign that was rising on the eastern horizon at your birth — it shapes your outer personality, appearance, and how others first perceive you.

    Do I need my exact birth time?+

    Yes — the Rising sign changes approximately every 2 hours, and house placements depend entirely on your birth time. Without it, you can get Sun, Moon, and planet sign readings, but the full psychological architecture (houses, Ascendant, Midheaven) won't be accurate.

    What is the Placidus house system?+

    Placidus is the most widely used house system in Western astrology. It divides the sky based on the time it takes for a degree to rise from the horizon to the midheaven, creating 12 unequal house divisions. AstroAsk uses Placidus for all natal chart calculations.

    What are aspects in astrology?+

    Aspects are specific angular relationships between planets — conjunctions (0°), oppositions (180°), squares (90°), trines (120°), and sextiles (60°) are the major ones. They describe how planetary energies interact in your chart — harmoniously, with tension, or with transformative power.

    What is the difference between Western and Vedic astrology?+

    Western astrology uses the tropical zodiac (based on seasons) and focuses on psychological depth, personality, and inner motivations. Vedic astrology uses the sidereal zodiac (based on actual star positions) and excels at life timing through the Dasha system. They complement each other — Western reveals who you are, Vedic reveals when things happen.
