Stelliums currently uses the five traditional configurations by zodiacal sign relationship: conjunction, sextile, square, trine, and opposition. The relationship is determined by the signs occupied by two planets.

• Conjunction — the planets occupy the same sign and their testimonies are concentrated together.
• Sextile — the signs are two signs apart and can support exchange or cooperation.
• Square — the signs are three signs apart and indicate pressure, contest, action, or a need for resolution.
• Trine — the signs are four signs apart and traditionally support continuity or mutual reinforcement.
• Opposition — the signs face one another across the zodiac and emphasize polarity, confrontation, or negotiation.

Why Stelliums labels this sign-based

A sign-based configuration is not the same thing as claiming a specific degree orb, application, or separation. Stelliums does not silently add those policies.
