Overview
In astrology, the word planet is used symbolically. The group commonly includes the Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto.
Astronomically, the Sun is a star and the Moon is Earth's natural satellite. In astrology, they are grouped with the planets because they function as major moving bodies in the chart.
Planets
What is happening in the chart.
Signs

Houses

Aspects
How the different chart pieces interact.

What to remember
- Planets are the moving parts of a chart.

Dignity and motion
Dignity, Retrograde, and Strength
Domicile
A planet occupies a sign it rules, suggesting direct access to its natural functions.
Exaltation
A planet occupies a sign where its function is traditionally strengthened or elevated.
Detriment
A planet occupies the sign opposite one of its domiciles and must work through a less natural style.
Fall
A planet occupies the sign opposite its exaltation and may require more conscious effort or support.
A retrograde planet is not automatically weak, negative, or damaged. It may be internalized, reviewed repeatedly, expressed less directly, or developed through reflection.
Timing
Speed, Returns, and Transits
Solar Return
Occurs once each year around the birthday and is used to examine themes for the coming year.
Lunar Return
Occurs approximately once every month and is used for shorter emotional and practical cycles.
Jupiter Return
Occurs approximately every 12 years and may emphasize growth, opportunity, education, belief, and expansion.
Saturn Return
Occurs approximately every 29 years and may emphasize responsibility, maturity, consequences, and restructuring.
A transit occurs when a moving planet forms a relationship with a natal planet, house, or angle. The transiting planet describes the pressure or opportunity, while the natal planet describes the function being activated.
Prominence
Planetary Strength and the Chart Ruler
The planet ruling the Ascendant is called the chart ruler. A planet may also become especially important when it repeats themes or connects strongly to angles, luminaries, or houses.
- Rules the Ascendant
- Conjuncts an angle
- Occupies an angular house
- Conjuncts the Sun or Moon
- Forms many tight aspects
- Rules several important houses
- Is part of a stellium
- Is strongly dignified
- Repeats themes found elsewhere in the chart
Method
Interpreting a Planet Step by Step
Planet + sign + house + aspects + rulership + real-life context
Common mistake
What Not to Overdo
- Treating planets as personalities.
- Treating the Sun as the whole chart.
- Treating benefics as always good.
- Treating malefics as always bad.
- Ignoring the house.
- Ignoring rulership.
- Treating retrograde as broken.
- Overemphasizing outer-planet signs.
- Predicting events from one planet.
