The angular relationships between the planets in a horoscope, measured as angles within the ecliptic circle, are termed “aspects”. Usually this includes angles to the ascendant and MC. Only certain angular relationships are regarded as aspects, and these are said to have intrinsic qualities – they are said to be “harmonic”, “dynamic” or “neutral”. These relationships influence how the planets work together. There is also a certain amount of “play”, which means that an aspect is said to “work” or be operative within a few degrees either way of being exact. This margin of “play” is defined by the orbs. (see below)
The conjunction tends to be a harmonious aspect. Its quality depends greatly on the planets involved, as well as on how close the aspect is. For example, a conjunction between the Sun and Mercury is generally regarded as harmonious. If, however, the distance between them is less than a few degrees, Mercury is said to be “burnt” or “in combustion”, with corresponding results. In general, the conjunction shows an immediate connection which usually works in one way or another.
Besides the major aspects mentioned above, there are also quite a number
of “minor aspects”. Most of these are subdivisions of the major
aspects. The minor aspects add depth and detail to the general picture.
The orbs permitted for the minor aspects are much smaller than those used
for the major aspects. (see table below)
The most common minor aspects are:
Semisquare - 45°, disharmonious
Sesquisquare - 135°, disharmonious
Semisextil - 30°, neutral
Quincunx or Inconjunct - 150°, neutral
Quintile - 72°, harmonious
Biquintil - 144°, harmonious
