Mars moves half a degree per year.Įach of these planets can spend years of a person's life in retrograde motion (in the progressed chart) if they were retrograde at birth or in the days or weeks following birth. Nearby planets (Venus and Mercury) move at a similar rate to the sun, though their movement is less consistent due to retrograde periods. The distant planets (Neptune and Pluto) move very little in a progressed chart. It moves one degree per year and only goes through two to three signs in most people's lives. In contrast, it takes 30 years for the progressed sun to change signs. It takes approximately 2.3 (often rounded to 2.5) years for the progressed moon to change signs and around 27.5 years for it to go through all the signs. It moves approximately one (1.09) degree(s) per month. The moon is the fastest-moving planetary body in the progressed chart (and one of the most useful). From that an astrologer can use the chart to interpret the character and dynamic of the relationship.Because progressed charts are used to show gradual changes and evolution, they hold their meaning longer than a standard "transit chart," another important predictive astrology chart.

Synastry charts are used to examine relationships between two people or, more specifically, how they may effect each other individually.

Synastry charts and composite charts are similar in that they both explore relationships. Each aspect shape produces a different meaning. An example of an aspect shape includes a square, trine, conjunction, and more. In a synastry chart, an aspect is the geometric relationship between the two sets of planets. The only difference being that there are twice as many elements being charted. Visually a synastry chart looks exactly like a birth chart - a 360 degree wheel divided into 12 sections. Basically it is overlaying two individual’s birth charts and examining the aspects between the two charts. Now when we overlay another individuals map over your map, we can visually see where their planets were located in relations to yours - that is the basis of a synastry chart. Think of a map of the cosmos that is a snapshot of the exact planetary coordinates of when you were born.
