The Aspects

Aspects are connections formed between planets depending on the degree of the Zodiac that they occupy. When the planets occupy the same degree of different signs, they have a connection that is either harmonious or challenging, depending on the signs involved, or the number of degrees separating the planets. Separations of 0, 90 and 180 degrees are considered challenging, while separations of 60, 72 and 120 degrees are considered flowing or easy. The "Major" aspects are considered the conjunction (0°), the opposition (180°), the square (90°), the trine (120°), and the sextile (60°). Minor aspects include the inconjunct (150°), another form of inconjunct, the semi-sextile (30°), the quintile (72°), the semi-square (45°), and another form of semi-square, the sesquiquadrate (135°). Although these are the degrees of separation when an aspect is exact, the "orb" of an aspect is how far off from exact it can be and still operate. Most practitioners use an orb of 7 to 8 degrees for major aspects, 1 to 2 degrees for minor aspects, and up to 12 degrees for major aspects with the Sun or Moon involved.

A complete list of the aspects used in TimePassages Astrology Software is given below, with their associated degrees. The theory of aspects is complex, including the phasal relationship represented by the number of degrees of separation, and whether the aspect is "waxing" or "waning" in analogy to the phases of the Sun-Moon relationship.
