Location and relationship
Aspects and orbs
Calculate the five major aspect angles and their orbs, then describe connection, ease, or friction without calling an aspect good or bad.
What you'll learn
- Name the exact angles of the five major aspects
- Calculate the shortest separation and orb between two planets
- Apply Astroyana’s 6° display rule without treating it as universal
- Interpret an aspect as a relationship between functions
An aspect starts as arithmetic. Here are the five relationships Astroyana displays in its Western Expert table:
| Aspect | Exact angle | | --- | ---: | | Conjunction | 0° | | Sextile | 60° | | Square | 90° | | Trine | 120° | | Opposition | 180° |
Those angles are the observable rule. Interpretation comes next: conjunction gathers functions; sextile offers cooperation; square asks for adjustment; trine describes easier flow or reinforcement; opposition sets up polarity or balancing. A trine is not a prize, and a square is not a punishment. Ease can go unused; friction can produce effort. Which planets are involved matters more than a good/bad label.
An orb is the distance from exactness. Astroyana uses a uniform 6° orb for these five planet-to-planet aspects in its Expert display. That is a clear product and teaching rule, not a universal standard. Historical practice often assigned different orbs to planets; modern schools and programs may vary the allowance by planet, aspect, or luminary.
Work the shortest distance
Our synthetic Sun is at 18° Leo and Moon at 20° Taurus.
- Convert each to longitude from 0° Aries. Leo begins at 120°, so the Sun is
120° + 18° = 138°. Taurus begins at 30°, so the Moon is30° + 20° = 50°. - Their absolute difference is
|138° − 50°| = 88°. It is already below 180°, so it is the shortest separation. If the first difference were over 180°, subtract it from 360°. - The closest major angle is the 90° square.
- The orb is
|88° − 90°| = 2°.
Observable result: Sun square Moon, 2° orb. A first interpretive sentence might say that purposeful visibility and habitual needs are in a close, frictional relationship that asks for adjustment. It does not predict conflict, and it cannot say how the tension is handled without more context.
Now calculate Sun at 18° Leo to Jupiter at 19° Sagittarius. Sagittarius begins at 240°.
Try it before you reveal it
What major aspect connects the teaching Sun and Jupiter, what is its orb, and which shortcut would give a weaker answer?
Compare your attempt
Worked answer
Jupiter's longitude is 240° + 19° = 259°. The separation from the Sun at
138° is 121°. That is a trine with a 1° orb. Merely saying “Leo and
Sagittarius are both fire, so they trine” is the weak shortcut: signs show the
broad relationship, but the degrees show whether the planets fall within the
declared orb and how close the aspect is.
A likely mix-up
Signs in the same element always form an in-orb trine.
Try a fresh case
Move Jupiter to 26° Sagittarius and retest it with Astroyana’s 6° orb.
Transfer beyond the orb rule
Move Jupiter to 26° Sagittarius. Its longitude becomes 266°, making the separation 128° and the distance from an exact trine 8°. Under Astroyana's 6° lesson rule, this pair is not displayed as a trine. A school using a wider orb might keep it. Neither result should be reported without naming the orb rule.
