Stellium
Stellium explains a school-defined concentration by sign, house, and body count. The sign-based four-planet rule passes; a separate conjunction-based rule.
Overview
A stellium is a concentration of several chart factors, but minimum count, same-sign versus same-house scope, and permitted bodies vary by school. The page separates calculation from interpretation and keeps this worked result conditional: the sign-based four-planet rule passes; a separate conjunction-based rule would need orb checks. Verification follows this declared method: Publish whether three or four planets are required, whether angles count, and whether 29° Aries plus 1° Taurus forms one cluster under the selected rule.

Definition and exact scope
a stellium is a concentration of several chart factors, but minimum count, same-sign versus same-house scope, and permitted bodies vary by school
Calculation or decision rule
publish whether three or four planets are required, whether angles count, and whether 29° Aries plus 1° Taurus forms one cluster under the selected rule
Worked case and illustrative near miss
☉ 4°♏, ☿ 11°♏, ♀ 19°♏, ♂ 27°♏; rule requires four planets in one sign. the sign-based four-planet rule passes; a separate conjunction-based rule would need orb checks.
Illustrative near miss: Three planets spread across one house but three different signs do not pass this declared sign-based rule.
School and variant boundary
A pattern exists only when every required geometric edge passes the same published inclusion rule.
Product, safety, and verification boundary
OpenFate can connect Stellium to the natal chart and reading flow where supported; the connection supplies evidence, not a guaranteed life result. Verification retains failed measurements and uncertainty, then revises interpretation rather than the receipt. Stellium cannot diagnose a person, remove consent, or guarantee an event.
