Western Aspect Grid

Calculate all active aspects between any set of planetary positions. Provide a dictionary of body names to tropical ecliptic longitudes. Uses standard modern Western orbs by default: major aspects 5°, sextile 3°, minor aspects 1.5°. Custom orbs can be provided per aspect type.

Request parameters

positionsrequired

object

Dictionary of body name to tropical ecliptic longitude (0-360). Example: {"Sun": 229.6, "Moon": 221.8, "Mars": 189.6}

orbsoptional

object | null

Custom orbs per aspect type. If omitted, uses standard modern Western orbs: major=5°, sextile=3°, minor=1.5°
