Two numbers. A more nuanced picture.
Astrodynes, also called Cosmodynes, translate established astrological rules into numerical scores for planets, signs and houses. They help astrologers compare relative emphasis within a chart.
Power
How strongly a planet or house is emphasized within the scoring system. High power means prominence—not necessarily a favorable influence.
Harmony / Discord
How the influence is characterized within the method. Positive net scores indicate greater harmony; negative net scores indicate greater discord. Neither number is a prediction by itself.
| Combination | Traditional interpretation |
|---|---|
| High power + harmony | Prominent themes expressed with greater ease |
| High power + discord | Prominent themes associated with greater tension or friction |
| Low power + harmony | Less emphasized themes expressed with greater ease |
| Low power + discord | Less emphasized themes associated with some tension and friction |
See power and harmony side by side
These illustrative planetary scores demonstrate why a single “good” or “bad” label misses the point.
Gold bars show relative Power; numbers show Power · net Harmony/Discord. Example values only—not a real horoscope.
In this example, Saturn has the greatest power and a strongly positive net harmony score. The Moon has less power and a negative net score. Within traditional Astrodyne interpretation, those are two distinct patterns to consider alongside the full chart.
How should I interpret a high or low score?
Scores are best compared within the same chart and calculation basis. The original page offers approximate ranges (for example, power above 40 as prominent and net harmony beyond ±20 as significant), but these are interpretive rules of thumb rather than universal thresholds.
Why are the Sun and Moon important?
The Astrodyne methodology assigns special weight to the luminaries. Their scores should be read in context with house placement, aspects and the rest of the chart.
How the scores are calculated
Astrodynes are calculated using defined astrological rules rather than a language model guessing planetary strengths.
House position and angularity
Planetary placement contributes to power. Angular, succedent and cadent houses are weighted differently in the traditional system.
Aspects and their orbs
Planetary relationships contribute power and harmony/discord. Aspect type and closeness affect their numerical weight.
Sign dignity and other rules
Traditional rulership, exaltation, detriment and fall contribute to the assessment, along with other specified factors in the calculation framework.
More about the calculation methodology
The existing methodology describes house position power, major and minor aspects with orb weighting, parallel aspects, sign dignities, mutual reception and exaltation-degree considerations. Stellar Moves uses published Brotherhood of Light material as a reference benchmark. Exact implementation details and house-system bases should be checked against the current application documentation.
Houses give the numbers context
House Astrodynes connect planetary emphasis to traditional areas of life. An empty house can still have an important score because its ruling planet contributes.
| House | Traditional subject | House | Traditional subject |
|---|---|---|---|
| 1 | Identity, body, vitality | 7 | Partnerships and contracts |
| 2 | Resources, finances, values | 8 | Shared resources, inheritance |
| 3 | Communication, siblings, learning | 9 | Philosophy, travel, education |
| 4 | Home, family, roots | 10 | Career and public role |
| 5 | Creativity, children, pleasure | 11 | Friends, groups, aspirations |
| 6 | Daily work, habits, health symbolism | 12 | Solitude, hidden matters |
For example, an astrologer exploring career themes might examine the 10th house together with its ruler and the relevant planetary scores. The figures are interpretive indicators, not guaranteed outcomes.
One analytical foundation. Multiple applications.
Astrodynes began as a way to quantify chart factors. Stellar Moves uses that foundation across several workflows—not just relocation.
Relocation & location comparison
Compare relocated house emphasis and planetary power/harmony scores across places. The planets retain their zodiacal positions while house relationships change with location.
Forecasting & timing
Read transits, progressions, directions, profections and other timing techniques in the context of the natal chart's calculated strengths and tensions.
Relationships & groups
Explore relationship charts and Davison-based group or location work with structured chart evidence and context.
AI-assisted synthesis
Advanced readings can combine the calculated Astrodyne picture with multiple astrological techniques to highlight converging themes.
The purpose is not to replace astrological judgment, but to give the reader a consistent quantitative framework for deciding which chart factors deserve attention.
A method with a long history
Astrodynes were developed within the Brotherhood of Light tradition associated with C. C. Zain, the pen name of Elbert Benjamine. The aim was to establish repeatable numerical procedures for evaluating the strength and quality of astrological factors.
“Cosmodynes” is a commonly used alternate name. The methods were historically labor-intensive to calculate by hand; modern software makes comparisons practical across many charts and locations.
