In astrocartography, planets have varying effects depending on the angle or position they occupy on the map. Each planet’s influence is expressed differently when it aligns with the Ascendant (ASC), Descendant (DSC), Midheaven (MC), or Imum Coeli (IC). Understanding these variations helps you interpret how locations impact your life.

1. Ascendant (ASC) Position

• Planets on the ASC line influence self-expression and personality.
• Example: Mars-ASC → Increased assertiveness and energy; Mercury-ASC → Enhanced communication and sociability.

2. Descendant (DSC) Position

• Planets on the DSC line affect relationships and partnerships.
• Example: Venus-DSC → Harmonious and loving connections; Saturn-DSC → Serious, challenging, but stabilizing partnerships.

3. Midheaven (MC) Position

• Planets on the MC line influence career, reputation, and public life.
• Example: Sun-MC → Recognition and leadership; Jupiter-MC → Career growth and opportunities.

4. Imum Coeli (IC) Position

• Planets on the IC line affect home, family, and inner emotional life.
• Example: Moon-IC → Emotional security and connection to family; Venus-IC → Comfort and harmony at home.

5. Combining Planet and Position Effects

• Each planet brings its core energy (e.g., Venus = love, Mars = action).
• The line angle modifies how that energy is expressed (self-expression, relationships, career, or home).
• Example: Mars-MC → Ambition and drive manifest in career; Mars-IC → Active energy at home, possibly conflicts or household projects.

By analyzing the planet and its position together, you can gain precise insight into how different locations amplify, challenge, or transform your life experiences.
