The Major Aspects
Major aspects, also known as Ptolemaic aspects , are the most important angular relationships between planets in a birth chart. These aspects intermingle energies in clear and obvious ways , making them the most noticeable dynamics in our daily lives.
The more exact the aspect (i.e. the closer it is to the exact angle, such as 90° in a square), the stronger its effect . This makes them major themes that influence how planets, elements, and dynamics fit together in a birth chart.
In astrology, these aspects are five:
• Conjunction (0°) :
The planets are in the same degree or very close to each other, usually in the same sign . This is the purest conjunction, as the planets share the same element and modality.
In exceptional cases, a conjunction between two planets in adjacent signs may occur, but there must be a very small orb (margin of separation), usually up to 5°. In this case, the energies merge, but with greater contrast.
• Opposition (180°) :
The planets are in opposite signs, separated by six signs . For example, a planet in Aries will be in opposition to another in Libra.
This aspect generates a tug of war between energies seeking balance, since they belong to complementary axes in the zodiacal wheel (fire-air or earth-water).
• Quadrature (90°) :
Planets are three signs apart. For example, a planet in Taurus will be square to another in Leo or Aquarius.
This aspect indicates tension and challenges as it connects signs of different elements and modalities, creating friction that drives growth.
• Trine (120°) :
The planets are separated by four signs , always in the same element. For example, a planet in Gemini will be in trine with another in Libra or Aquarius, since all three are air signs.
This aspect represents fluidity and ease; energies flow naturally between the planets.
• Sextile (60°) :
Planets are separated by two signs , connecting compatible elements (fire with air or earth with water). For example, a planet in Aries will be in sextile with one in Gemini or Aquarius.
This aspect signals opportunity and cooperation, but requires a conscious effort to harness the potential.
The Minor Aspects
Minor (or non-Ptolemaic ) aspects are more subtle angles than major aspects, but equally valuable for understanding the nuances of a birth chart. They represent specific details and qualities that complement the main dynamics , enriching the overall interpretation.
Although minor aspects are not usually felt as clearly as major ones, their influence can be significant, especially when they are repeated in a birth chart or are part of specific configurations. The more exact the aspect, the greater its impact.
Some of the best known minor aspects are:
• Inconjunction or Quincunx (150°) :
This aspect connects planets separated by five signs , usually between elements and modalities that have no direct relationship. This generates a feeling of imbalance or discomfort, requiring constant adjustments to integrate the energies.
Although it is a minor aspect, if it is part of a configuration called yod it becomes more relevant (we will explore this topic in another blog entry).
• Semisextile (30°) :
The planets are separated by a sign . Although they are close, their elements and modalities are different, creating a slight connection. This aspect suggests gradual learnings that are not always obvious, but over time can become opportunities for growth.
• Semi-square (45°) :
The planets are separated by a sign and a half . This aspect creates a slight tension, a subtle push that motivates small changes or necessary adjustments.
• Sesquiquadrature (135°) :
The planets are separated by four and a half signs , creating a tension similar to the semi-square, but with a more dynamic and noticeable impact. This aspect can manifest itself in the need to restructure certain areas of life to overcome blockages.
Quintile.
Biquintile.
• Quintile (72°) and Biquintile (144°) :
These aspects separate planets by two and a half signs (quintile) or five signs (biquintile) . They are related to creativity, talent, and unique expression, connecting energies in unusual and harmonious ways. They often indicate special gifts or abilities that, if worked on, can excel in an exceptional way.
