Planets, signs, houses & aspects
Learn a repeatable path from chart data and components to interpretation, synthesis and timing.
Planet = what · sign = how · house = where
This shorthand is a teaching convention, not an astronomical law. A planet can be treated as a function or theme, its sign as the style of that function, its house as the life area where it is expressed, and an aspect as a relationship between two factors.
AstroOne’s current narrative layer follows this same kind of structure: for example Mars is tied to drive and assertion, Mercury to thinking and communication, and Saturn to responsibility and limits.
- Sun — identity and core direction
- Moon — emotional needs and instinctive response
- Mercury — thinking, learning, communication
- Venus — values, attraction, relating
- Mars — drive, desire, assertion
- Jupiter — growth, confidence, opportunity
- Saturn — discipline, responsibility, limits
- Uranus / Neptune / Pluto — change & disruption / imagination & ideals / deep change & regeneration
AstroOne’s houses and aspects
AstroOne Western Natal uses Whole Sign houses: the entire sign containing the Ascendant becomes House 1, and each following sign becomes the next house. That is the product’s current method, not a universal rule across all house systems.
Natal aspects are limited to conjunction 0°, sextile 60°, square 90°, trine 120° and opposition 180°. The fixed natal-orb policy starts at 8° for conjunction/opposition, 6° for square/trine and 4° for sextile, with a 1° allowance when the Sun or Moon is involved. This is AstroOne-specific configuration.
Do not reduce aspects to “good” and “bad”
Modern Western practice often treats trines/sextiles as easier flow, squares/oppositions as friction that asks for adjustment, and conjunctions as a strong blending of functions. But the planets involved and the rest of the chart matter more than a simple “benefic/malefic” label.
No single house system is taught as universally correct
Western astrology uses multiple house systems—Whole Sign, Equal, Placidus, Regiomontanus and others—and astrologers do not all choose the same one. AstroOne’s use of Whole Sign is therefore presented as a method choice, not as proof that other systems are invalid.
Reading Mars as a layered factor
- Input
Example A: Mars 24.37° Aries, Whole Sign House 10.
- Calculation
The longitude falls in Aries, and with Cancer rising in the Whole Sign layout, Aries is House 10.
- Factors to inspect
Planet function = drive/assertion · sign style = direct/initiating · house context = career/public role.
- Reasoning
Instead of stopping at “Mars = aggressive,” combine what the function does, how it acts, and where it is most visible.
- Synthesis
A reasonable hypothesis is a strong urge to initiate and act directly in career or public-responsibility contexts. In the synthesis lesson we will modify that hypothesis by adding the Moon-square-Mars aspect.
A keyword is not the final interpretation. The reading becomes more specific only after the layers and relevant aspects are combined.
