In the first post of the series, I mentioned that you are not a single function—you are an orchestra of ten. In the second, we looked at the three most important ones: the Sun, the Moon, and the Ascendant. It's time to see the whole orchestra.
Ten celestial bodies are working simultaneously in your natal chart. Each performs a different function. The Sun says who you want to be. The Moon how you feel. Mercury how you think. Venus what you love. Mars how you act. Jupiter where you grow. Saturn where you face your limits. Uranus what makes you rebel. Neptune where you dream. Pluto what transforms you.
Ten different functions. And each is a real part of you. Not a dominant zodiac sign. Not a main planet. Ten parallel processes happening simultaneously inside you.
This post is the third in our series of astrology lessons. Its goal is to teach you what each of the ten planets does, and to help you start reading them together. Not just looking at your Sun sign and calling it a day.
Why Planets, Not Signs
When most people hear "astrology", they think of their zodiac sign. When an astrologer hears "astrology", they think of the planets.
This isn't professional snobbery. There's a real reason. The zodiac sign describes only one parameter—the position of one out of ten celestial bodies. The planets describe ten different functions of the psyche. Two people with an Aries Sun can have completely different Venus, Mars, Mercury, and so on. That's why one might be a direct fighter and the other a delicate diplomat, even though they formally share the same sign.
The zodiac sign describes the goal you consciously pursue. The planets describe the tools you use to pursue it. You can chase the same goal with ten different orchestras, and each will sound completely different.
The Three Groups: Personal, Social, and Outer Planets
The ten planets are not all the same. They move at different speeds and describe different levels of your life. Astrologers group them into three categories.
Personal planets make you exactly who you are. Social planets connect you to society. Outer planets belong to your generation.
Personal planets are five—Sun, Moon, Mercury, Venus, and Mars. They move quickly (from one day to about a month per sign) and describe your individual character. They make you exactly who you are, and no one else replicates their exact distribution.
Social planets are two—Jupiter and Saturn. They move more slowly (about a year per sign for Jupiter, about two and a half for Saturn) and describe how you fit into society. You share them with an entire age cohort of people born in nearby years.
Outer planets are three—Uranus, Neptune, and Pluto. They move so slowly (from 7 to over 30 years per sign) that they describe themes of entire generations. By themselves, they do not describe you as an individual. They describe the zeitgeist of the era you were born in.
This three-tiered hierarchy is critical for properly reading a natal chart. Personal planets tell you who you are. Social planets tell you how you handle society. Outer planets tell you which generation you belong to. Without this hierarchy, it's easy to take Uranus in Scorpio as a personal "characteristic", when in fact you share it with a few hundred million other people.
Personal Planets — The Five That Make You
The Sun: The Goal
The Sun is the direction in which you consciously grow throughout life—not the point where you currently stand. It describes the ego, willpower, and the goal of personal development. Until about age thirty, the Sun develops slowly. After that, it becomes increasingly visible.
I covered the Sun in depth in the post on the Big Three—there I explained why it doesn't describe your current personality, but the direction of your growth.
The Moon: The Starting Point
If the Sun is the goal, the Moon is the starting point. It describes your emotional nature, the need for safety, instinctive reactions, and the version of you that appears when you are stressed or alone.
The Moon was also covered in the post on the Big Three. There I explained why it is often the "truer" side of the personality—because it is less conscious.
Mercury: The Voice of the Mind
Mercury describes how you think and how you communicate. The speed at which you process information. The style in which you speak. The way you make decisions. Whether you think in words or in images. Whether you understand through analysis or intuition.
Mercury cannot be far from the Sun. It is always in the same sign as the Sun or in an adjacent one. This means Mercury can amplify or soften the Sun sign.
Mercury in Gemini or Virgo is in domicile—its ruling sign—and works at full strength. Quick mind, multitasking, love for words. Mercury in Pisces or Sagittarius is in detriment—it sees the big picture but struggles to focus on details.
There is no such thing as a bad Mercury. There are different styles of thinking. Mercury in Aries thinks fast and directly. Mercury in Taurus thinks slowly and steadily. Neither style is better—they simply solve different problems.
Venus: What You Love
Venus describes what attracts you—aesthetically, romantically, and socially. What you find beautiful. What style you like. How you express affection. What type of partner you look for on a taste level (not a goal level—the goal is the Sun).
Venus has much less to do with your zodiac sign than most people assume. A Leo Sun with a Virgo Venus will want grand, showy gestures, but will actually be attracted to practical, modest people with a neat style. This mismatch between "what I want my love to look like" and "what actually attracts me" is one of the most common surprises when someone reads their natal chart for the first time.
Venus also describes values—what you find worthy, what is worth time and money in your eyes. Here, a Venus in Scorpio (intensity, depth) will value entirely different things than a Venus in Gemini (variety, novelty).
Mars: How You Act
Mars describes energy, action, desire, and rage. How you pursue what you want. How you defend yourself when attacked. How you express your sexual energy. What motivates you to get up in the morning.
Venus and Mars are a partnership pair. Venus says what you want. Mars says how you will get it. Venus in Libra wants a harmonious relationship. Whether they pursue it diplomatically or aggressively depends on Mars. Mars in Gemini will talk a lot, argue, and persuade. Mars in Scorpio will act strategically without showing their cards.
Mars in domicile (Aries or Scorpio) is pure, direct, clear. Mars in detriment (Libra or Taurus) is often perceived as slow or indecisive—but it is actually just more careful and tactful. Never underestimate a quiet Mars.
Social Planets — How You Fit Into the World
Jupiter: Expansion
Jupiter describes where in your life the natural "yes" is located. Where you grow easily. Where you get lucky. Where you have confidence. Where you are generous and optimistic.
Jupiter is not unconditionally beneficial. It is the principle of expansion, and whatever is already there, it makes more of it. Jupiter in the right place increases generosity and luck. Jupiter in the wrong place increases boasting and disregard for consequences. That's why they say Jupiter is "beneficial only in moderate doses".
Jupiter changes signs about once a year. This means that every year of your life has a Jupiter theme—an area where expansion is easy just for you. This theme coincides with the house that transiting Jupiter is passing through.
Saturn: Limitation
Saturn is the opposite of Jupiter. It describes where in your life the natural "not yet" is located. Where you face limits. Where lessons come with difficulty. Where you are required to build structure and discipline.
Saturn is a lifelong teacher, and that is exactly why it is one of the most important planets in the natal chart. Liz Greene, one of the most influential psychological astrologers of the 20th century, dedicated an entire book to this planet—"Saturn: A New Look at an Old Devil" (1976)—in which she overturned the standard view. Saturn is not bad luck, nor a punishment. It is the principle that makes you earn what you have. And if you accept its lesson at the right time, you become strong. If you avoid it, the experience repeats until you accept it.
Around the twenty-ninth year of life, transiting Saturn makes a full orbit and returns to its natal position. This is called the Saturn Return and is usually the first major crisis of adulthood. Until this age, a person lives under the expectations of others. After it, they begin to live under their own structure. Painful, but necessary.
Outer Planets — Generational Themes
Uranus, Neptune, and Pluto move so slowly that by the signs themselves, they do not describe an individual—they describe an entire generation of people born in nearby years.
Uranus changes signs about every seven years and describes the rebellion of the generation—where this generation opposes established forms. People born with Uranus in Libra (1968-1975) rewrote the rules of marriage and partnership. People with Uranus in Scorpio (1975-1981) changed attitudes toward sex, death, and taboo. These themes are not yours individually—they belong to your generation.
Neptune changes signs about every fourteen years and describes collective illusions and ideals. Where the generation dreams. People born with Neptune in Sagittarius (1970-1984) dreamed of freedom without borders—globalization, open societies. People with Neptune in Capricorn (1984-1998) dream of stability and material security. Both are valid dreams. Both are generational, not personal.
Pluto changes signs at intervals of 12 to over 30 years and describes the deep transformations the generation goes through. Pluto in Scorpio (1983-1995) saw the end of a world order (the Cold War) and the beginning of a new one. Pluto in Sagittarius (1995-2008) rewrote what faith, ideology, and truth mean. These changes happened through you if you were born in the respective period, not by you.
Outer planets influence the individual through houses and aspects, not through signs. Uranus in the tenth house (regardless of sign) activates a rebellion against career authorities. Pluto in the seventh house creates transformative partnerships. Neptune in the sixth house blurs the boundaries of daily work and health.
In other words, if you want the outer planets to tell you something personal, don't look at the sign—look at the house and aspects.
How to Read the Planets Together
Now you have ten tools. How do you use them together?
One working method is this. First, look at your personal planets—they make you exactly who you are. Then see how Jupiter and Saturn shape how you manifest in society. Finally, recognize the generational background of the outer planets, without confusing it with your personality.
For example: Sun in Aries (you want to lead) + Moon in Cancer (emotionally sensitive) + Mercury in Aries (you think fast, speak directly) + Venus in Taurus (you like sensory beauty, stability) + Mars in Gemini (you act through words, not fists) + Jupiter in the tenth house (growth through career) + Saturn in the seventh house (lessons come through partnerships) + Uranus/Neptune/Pluto according to generation.
This is a person who wants to lead but is emotionally sensitive. Thinks and speaks directly, but in love seeks peace and beauty. Acts through argument, not force. Finds luck in their career but must build maturity in partnerships. A level of complexity that a zodiac sign can never describe.
This is a real reading of a natal chart. And this is exactly what TarotScope does.
Frequently Asked Questions
What is the difference between a planet in a zodiac sign and a planet in a house?
The sign tells you how the planet acts; the house tells you where in life it acts. Venus in Libra (harmonious, balanced) in the seventh house (partnership) will create harmonious partnerships. The same Venus in Libra in the tenth house (career) will create harmonious professional relationships. Different house, different area of life.
Why is Pluto a planet in astrology if it isn't in astronomy?
Because astrology does not describe the cosmos physically. It uses celestial bodies as symbols for psychological functions. When the International Astronomical Union downgraded Pluto to a "dwarf planet" in 2006, nothing about its astrological function changed. Pluto continues to describe transformation and depth—factually for astronomy, symbolically for astrology.
What is a retrograde planet?
Retrograde means that from Earth, a given planet appears as if it is moving backward in the zodiac. This is an optical illusion, not actual movement. In the natal chart, retrograde planets indicate that the energy of this function is directed inward—before it manifests externally, it goes through introspection. Mercury retrograde in the natal chart means you think more slowly, but often more deeply. Venus retrograde—you love more carefully, more reservedly. It's not a defect. It's a different operating model.
Are there planets that are not important?
No. All ten describe a real function within you. What changes is how strongly each manifests. A planet on an angular house (1, 4, 7, 10) is more visible. A planet in its domicile acts purely. A planet in detriment works differently than the standard. But none is "unimportant." It simply plays its instrument quieter or louder in your orchestra.
Which planets change quickly and which slowly?
The Moon changes sign every 2-3 days. The Sun every 30 days. Mercury and Venus every 3-4 weeks. Mars about every 2 months. Jupiter every 1 year. Saturn every 2.5 years. Uranus every 7 years. Neptune every 14 years. Pluto from 12 to 30+ years. This is exactly why the slow planets describe more general themes, and the fast ones—more individual ones.
In the fourth post of the series, we will look at the 12 houses—the stages on which all ten planets play different roles. Because if the planets are the actors, the houses are the sets.
