Line Guide

Astrocartography Lines Explained

Every planet in your birth chart draws four lines around the Earth — one for each angle of the local sky. Pick a planet below for a deep guide to what its MC, IC, ASC, and DSC lines mean in practice.

The Four Angles, in One Minute

  • MC (Midheaven) — the planet was overhead. Career, reputation, and your place in society.
  • IC (Imum Coeli) — the planet was underfoot. Home, family, roots, and inner foundation.
  • ASC (Ascendant) — the planet was rising. Identity, body, vitality, and how you come across.
  • DSC (Descendant) — the planet was setting. Partnerships, and the people a place brings into your life.

Reinvention and radical independence — where the script gets rewritten.

Imagination, spirituality, and dissolving boundaries — inspiration and fog in equal measure.

Death-and-rebirth intensity — where transformation stops being optional.

Growth direction — where life pulls you toward unfamiliar but necessary territory.
