Out-of-sign aspect
Each of the classical aspects goes with a relationship between signs. A trine normally joins two signs of the same element, a square two signs of the same modality, an opposition two opposite signs, a conjunction one sign. An out-of-sign aspect — often called dissociate — is one where the planets are within orb by degree, but at the edges of their signs, so the signs themselves are not the ones the aspect normally links.
Worked examples
- Conjunction across a sign line. The Sun at 29° Cancer and Mercury at 2° Leo are 3° apart: a conjunction by degree, but one planet is in a water sign and the other in fire.
- Square between trine signs. Venus at 28° Gemini and Mars at 1° Libra are 93° apart — a square with a 3° orb. Yet Gemini and Libra are both air signs, a trine relationship by sign.
- Trine between different elements. The Moon at 29° Cancer and Jupiter at 1° Sagittarius are 122° apart: a trine by degree between water and fire.
How it is read
In the oldest tradition, aspects belonged to the signs: Ptolemy explains each one by how the signs relate, and a planet in a sign was in aspect to anything in a sign that "beheld" it. On that view an out-of-sign contact is weak, or not counted at all. Most modern astrologers count aspects by degree, so they keep the contact but note that it has a mixed quality: the angle says one thing and the signs another. A dissociate square between two air signs often feels less like a clash of tempo than a disagreement between two similar minds; a dissociate trine works, but with less of the shared nature that usually makes a trine easy. deVore notes that "dissociate" was once a name for the quincunx, and now means any aspect formed out of its expected signs.
Here
The charts here count aspects by degree, so an out-of-sign aspect appears like any other, with its orb and strength. Where this entry shows the contacts in your own chart, those that fall across unexpected signs are picked out. Aspects that span a sign and a half or more — the semi-square, sesquiquadrate, quintile and biquintile — have no fixed sign pairing, so the idea does not really apply to them; nor does it apply to parallels, which are measured in declination.
