Astrological Personality and Planets

Astrology is a tool that helps us understand how we think, act, relate, and love. When we interpret our birth chart, we realize that many planets besides the Sun and the Moon influence our astrological personality. Find out which ones and how they do it.

The word planet evolved from a Greek word meaning “wanderer.” The planets owe their names to classical mythology: Mercury, Venus, Mars, Jupiter and Saturn, Uranus, Neptune, and Pluto. For Astrology, the Sun and the Moon are also considered planets.

The Elements and the Planets

Like the signs, the planets are also linked to the Elements, one of the fundamental aspects of astrological symbology. Each planet governs one of the Zodiac Signs prints its symbolic energy.

The signs correspond to the constellations in the sky, which the Sun illuminates as it passes through the ecliptic. The ancient planets (that is, the planets known in antiquity) are related to specific deities of mythology, which, in turn, represent areas of life and personality archetypes.

The Primitive Qualities and Characteristics of Planets

The Primordial Qualities (Hot and Cold / Dry and Wet) are the basis of all the energetic symbology present in astrology. Inspired by the characteristics of nature and matter, they subtly regulate cosmic energy.

  • Qualities: Hot and Dry
  • Element: Fire
  • Temperament: Choleric
  • Qualities: Cold and Humid
  • Element: Water
  • Temperament: Phlegmatic
  • Qualities: Mercury does not have a defined quality since it tends to absorb the qualities it comes into contact with. However, it is considered “Cold and Dry when viewed in isolation without any other influence.”
  • Element: Earth
  • Temperament: Melancholic
  • Qualities: Cold and Humid
  • Element: Water
  • Temperament: Phlegmatic
  • Qualities: Hot and Dry
  • Element: Fire
  • Temperament: Choleric
  • Qualities: Hot and Humid
  • Element: Air
  • Temperament: Bloody
  • Qualities: Cold and Dry
  • Element: Earth
  • Temperament: Melancholic

Modern planets (Uranus, Neptune, and Pluto) and Chiron have not been attributed these attributes. These date back to the beginning of astrological studies when they were still unknown because they were not visible to the naked eye.

Or, to put it another way:

  • Sun and Mars - “Hot and Dry”
  • Saturn and Mercury - “Cold and Dry”
  • Venus and the Moon - “Cold and Wet”
  • Jupiter - “Hot and Wet”

The Action of the Planets in the Personality of the Signs

Knowing the astrological meaning of the planets present in our birth chart helps us know the various facets of our personality, tendencies, and potentials. This self-knowledge allows us to work on the most unfavorable traits that potentially hamper our total growth.

In the birth chart, the planets are placed in a House (which represents the various spheres of our life) and in a sign. The planets emphasize the sign’s energy to express itself in the house.

That is, the planets use the sign’s energy to express themselves in a specific area of life. For example, having Venus in Pisces in the 10th house means that the potential of Venus uses the energy of Pisces to express itself in your career and in the way you approach the problems of professional success.

Among the planets, we have the Aspects that indicate the relationships between the different areas of life (between the Houses), the energies between the planets, and the energies between the signs.

Imagine a person who was born on February 25. The sun sign is Pisces since the Sun was in Pisces’ zodiac zone.

However, the Moon (which governs the emotions) was in Aries, Mercury (ruler of the mind), Scorpio, Mars (ruler of physical strength), Taurus, and Venus (ruler of relationships) in Capricorn, and so on, with the other planets.

In this example, although the base personality is Pisces, the various nuances of this person’s personality would reflect the specific characteristics of each of the planets present in their birth chart.


Influence of the Planets on the Personality of the Signs


  • Sign: Leo
  • Area of Influence: Personality, main concerns, vitality

The Sun represents our basic astrological personality, identity, ego, and consciousness. We know our sign through its position at the time of our birth. It is, therefore, our main sign. The central archetype of our personality and the most powerful indicator of who we are.


  • Sign: Cancer
  • Area of Influence: Emotions, instincts, habits

The Moon represents our emotional, sensitive and subconscious nature. The Sun is how we see ourselves for some astrologers, and the Moon reflects who we are. Of all the planets, the Moon is the one to pay the most attention to. After all, it’s about preserving our emotional well-being. The Moon changes sign every two and a half days.

Inner Planets - Mercury, Venus, and Mars

The inner planets, or personal planets, represent the main facets of our astrological personality. Mercury rules the mind, Venus the loving nature, and Mars the impulses. The location where these planets are located in our birth chart reveals how we express various energies.


  • Signs: Gemini and Virgo
  • Area of Influence: Communication, intellect, reason

Mercury rules the mind, intellect, and communication. This planet indicates how we speak, learn, write, and reason—our intellectual interests, curiosity to learn, or how we assimilate new knowledge.


  • Signs: Taurus and Libra
  • Influence Area: Love, beauty, art

Venus rules loving nature, values, and creativity. This planet reflects harmony, beauty, art, and abundance. It reflects our strength of attraction, charm, and success in social relationships. The position of Venus in our birth chart indicates how we relate to aesthetics, relationships, and wealth.


  • Signs: Aries and Scorpio
  • Area of Influence: Action, desire, aggression

Mars rules physical exertion, attractions, and sexuality. The positioning of this planet in our birth chart reflects our urges and sexuality. It shows our most basic instincts: what attracts us and what dislike. It reflects how we behave in our emotions.

Social Planets - Jupiter and Saturn

Social planets, less personal than previous planets, reflect how we relate to the outside world. Jupiter rules religion, philosophy, and humor, while Saturn rules society, government, and traditions.


  • Signs: Sagittarius and Pisces
  • Area of Influence: Expansion, optimism, abundance

Jupiter is the most cheerful, lively, and the fun planet. It represents humor, abundance, optimism, generosity, expansion, and luck. Leadership, enthusiasm, financial stability are some of the positive energies of this planet that are reflected in our astrological personality.


  • Signs: Capricorn and Aquarius
  • Area of Influence: Restriction, pessimism, structure

Saturn is the planet of obstacles, responsibility, and ambition. The adversities present to us throughout life allow us to grow and mature personally.

This planet helps us think about our decisions in the face of a dilemma, failures and learning for the future. In our birth chart, the sign-in which Saturn is found reveals the challenges we have to face and what we must work on to achieve our goals.

Outer Planets - Uranus, Neptune, and Pluto

These three distant planets from Earth represent the most esoteric aspects: the mystical and hidden qualities of life that push us from our comfort zone to a higher level of existence. Uranus rules intuition and the future, Neptune rules healing and spirituality, Pluto is power and transformation. They are magical planets that bring depth and greatness to our lives.


  • Sign: Aquarius
  • Area of Influence: Rebellion, eccentricity, agitation

Uranus is the planet of intuition, revolution, and the future. The influence of this planet on our astrological personality leads us to test our limits and take risks. It encourages us to want more and in a different way, to make revolutions and break with a past that does not serve us. Innovation, creative genius, and resourcefulness are expressions of the presence of Uranus energy in our lives.


  • Sign: Pisces
  • Area of Influence: Imagination, dreams, illusions

Neptune is the planet of healing and spirituality. It is a mystical, sensitive and pious planet that reveals our most profound energies. It governs dreams and illusions. Positively, it elevates our creative spirit, and it is the patron of artistic expression and harmony. Negatively, it can lead to credulity, impracticality, and illusion.


  • Sign: Scorpio
  • Area of Influence: Transformation, obsession, power

Pluto, the “dwarf planet” of our Solar system, represents power and transformation. It is the most powerful planet in Astrology, and it governs death, rebirth, and transformation. It closes and starts movements when passing from one sign to another. It reflects each generation’s difficulties, passions, and changes on Earth.


  • Sign: Not assigned
  • Area of Influence: Suffering, dilemma, resignation, fusion, healing

Chiron’s highly eccentric orbit has associated it with the concept of a bridge that unites worlds, with the integration between two realities, two opposites, with dilemmas. This star represents the union between the spontaneous “I” and self-awareness, the will to solve personal dilemmas and paradoxes. However, given its recent discovery, its astrological significance is still discussed.
