Ptolemaic Aspects

Since they were defined and used by

Ptolemy Claudius Ptolemy (; , ; ; – 160s/170s AD) was a Greco-Roman mathematician, astronomer, astrologer, geographer, and music theorist who wrote about a dozen scientific treatises, three of which were important to later Byzantine science, Byzant ...

in the 1st Century AD, the traditional major aspects are sometimes called Ptolemaic Aspects. These aspects are the Conjunction (0°), Sextile (60°), Square (90°), Trine (120°), and Opposition (180°). Major aspects are those that are divisible by 10 and evenly divided in relation to 360° (with the exception of the Semisextile and the Novile). When calculating or using aspects, it is important to note that different astrologers and separate astrological systems/traditions utilize differing orbs, which is the degree of separation between exactitude. Orbs may also be subject to variation, depending on the need for detail and personal preferences. Although, when compared to other aspects, almost all astrologers use a larger orb for a Conjunction.

Highly favourable Conjunctions may involve the Sun,

If either of two planets involved in a Conjunction is also under tension from one or more hard aspects with one or more other planets, then the added presence of a Conjunction will further intensify the tension of that hard aspect. If a planet is in ''very'' close Conjunction to the Sun (within 17 minutes of arc or only about 0.28°), the Conjunction is of great strength. The planet is said to be ''Cazimi'', which is an ancient astrological term meaning "in the heart" (of the Sun). For example, "Venus ''Cazimi''" means Venus is in Conjunction with the Sun with an orb of less than ~⁠0.28°.

. Every 20 years, successive Great Conjunctions move retrograde ~120°. Sequential Conjunctions appear as triangular patterns. They repeat after every third Conjunction; they return after some 60 years to the vicinity of the first. These returns are observed to be shifted by ~8° relative to the fixed stars; no more than four of them occur in the same zodiac sign. Typically, Conjunctions occur in one of the following '' Triplicities'' or ''Trigons'' of

Opposition

An Opposition (abbreviated as "Opp") is an angle of 180°, which is of the 360°

. Depending on the involved planets, an orb of 5-10° is allowed. An Opposition is said by Ibn Ezra to be the most powerful aspect. An opposition is fundamentally relational but not unifying or blending like a conjunction. Some astrologers say the energies in opposition are prone to exaggeration, because it has a dichotomous quality and issues arising from it are often tense. All important axes in astrology are essentially Oppositions. Therefore, at its most basic level, an Opposition may often signify a relationship that can be oppositional or complementary.

Sextile

or a trine (120°). Depending on the involved planets, an orb of 4-5° is allowed. The symbol is the radii of a hexagon. Traditionally, a Sextile is said to be similar in influence to a Trine, but less intense. It indicates compatibility and harmony, which eases communication between the two involved elements. It also provides opportunity. See information below on the Semisextile.

Square

A Square or ''Quartile'' (abbreviated as "SQr or Squ") is an angle of 90°, which is of the 360°

Minor aspects

Semisextile

A Semisextile or ''Duodecile'' is an angle of 30°, which is of the 360°

Of the minor aspects, it may be the most often used, because it can be easily seen. It indicates a mental interaction between planets; it is more sensually than externally experienced.

Semioctile

A Semioctile or ''Sexdecile'' is an angle of 22.5°, which is of the 360°

. An orb of ±0.75° is allowed. A Semioctile is part of the square family. It is considered to be a version of the Semisquare, which triggers challenge. Its harmonic aspects are 45°, 67.5°, 90°, 112.5°, 135°, 157.5° and 180°. It was discovered by Uranian astrologers. ;Irreducible Multiples: : A Sesquioctile or ''Bisexdecile'' is an angle of 67.5°, which is of the 360° ecliptic. : A Quinsemioctile or ''Quinsexdecile'' is an angle of 112.5°, which is of the 360° ecliptic. : A Sepsemioctile or ''Sepsexdecile'' is an angle of 157.5°, which is of the 360° ecliptic.

Declinations

The Parallel and Contraparallel or ''Antiparallel'' are two other aspects which refer to degrees of

declination In astronomy, declination (abbreviated dec; symbol ''δ'') is one of the two angles that locate a point on the celestial sphere in the equatorial coordinate system, the other being hour angle. The declination angle is measured north (positive) or ...

Celestial Equator The celestial equator is the great circle of the imaginary celestial sphere on the same plane as the equator of Earth. By extension, it is also a plane of reference in the equatorial coordinate system. Due to Earth's axial tilt, the celestial ...

Parallel and Contra Parallel

A The same declination of two planets. The declination is the vertical angle between a planet and the celestial equator, in a southern (S) or northern (N) direction. Planets in a parallel relationship are compared to a conjunction. A contra parallel or "split" parallel occurs when two planets have the same number of degrees of declination, but in opposite hemispheres. For example, the moon might be at 20 degrees north latitude, while Pluto appears at 20 degrees south latitude. Its meaning is similar to that of the opposition.
