In astrology, orbs define the allowable degree range within which an aspect is considered effective. Understanding orbs is essential for interpreting planetary aspects accurately in a natal chart or during transits.
1. What Are Planetary Orbs?
- An orb is the range (in degrees) from the exact aspect where the interaction is still considered valid.
- Exact aspects → strongest influence.
- Wider orbs → weaker or more subtle influence.
- Orbs vary depending on planet type, aspect type, and chart context.
Key Principle:
- The closer to exact → stronger influence.
- The farther from exact → influence diminishes gradually.
2. Practical Orb Guidelines by Planet Type
Planet Type | Suggested Orb Range | Notes |
|---|---|---|
| Sun / Moon (Luminaries) | ±8–10° | Strong influence; wider orbs due to importance. |
| Mercury / Venus / Mars (Personal Planets) | ±6–8° | Affects communication, love, and action; tighter orb for precision. |
| Jupiter / Saturn (Social & Karma Planets) | ±6–10° | Influence extends over longer periods; wider orb acceptable. |
| Uranus / Neptune / Pluto (Outer Planets) | ±6–12° | Slow-moving; wider orbs capture long-term effects. |
