Last updated by Susan Taylor

The planet Mercury plays a huge part in the Astrology world and is at points responsible for cursing us with a heap of bad luck and misfortune when it goes retrograde. You just have to look at where it sits in birth charts to know how important it is to astrologers. Susan Taylor, our very own astrologer, tells us all you need to know about this intellectual planet and how much influence it exerts on us.

Mercury In Astrology, What Influence? What Effects Does It Have?

Mercury in Astrology: The intellect

This so-called "fast" planet represents in a natal chart our mind, our intellect, our way of thinking, our ease (or difficulty) in learning, and our way of analyzing. It is a cerebral planet, associated with reflection and expression. It can give clues about how we speak, write, and move. It can also symbolize finances and trade, as well as our son (if we have one), our brother, our friend, and the adolescence we experienced.

In astrology, a planet can exert a positive or negative influence depending on its position and movement, whether it is retrograde or not. When positively influenced, Mercury brings out the best of its abilities; otherwise, it can exert a very negative influence, for example, when Mercury is retrograde.

  • Positive influence of Mercury: Mercury symbolizes sociability, humor, flexibility, youth, intelligence, gift of expression, cleverness...
  • Negative influence of Mercury: carelessness, superficiality, lack of willpower, gossip, insensitivity, distraction, duplicity, instability, trickery, nervousness...
  • Symbolically: Mercury represents curiosity, association, encounters, money, studies, analysis, logic, medicine, lawyer, writer, brother, son...

Mercury in the zodiac signs: What influence does it have?

Where is Mercury located in your natal chart? Its position in a particular zodiac sign has an influence. Discover what it is.

Mercury in Aries

Your mind is inventive and bold, with ideas flowing one after the other. Generally, once you think of something, you act on it very quickly. You are a person of action and conviction. However, you may lack concentration and have too many interests, risking spreading yourself too thin and not delving deeply into your thoughts. When you express yourself, you don't beat around the bush. Your spontaneity and frankness can sometimes hurt others.

Mercury in Taurus

You think a lot before acting and avoid relying on chance or improvisation. You rely more on your analytical skills than on intuition. You have a practical, realistic mind, grounded in material reality. You take the time to study the ins and outs of a situation, deepening your knowledge, which can sometimes slow you down. However, you know how to organize, manage, focus on a goal, and see your ideas through to completion. On the negative side, you can be stubborn to the point of closing yourself off to other solutions or others' suggestions.

Mercury in Gemini

Mercury is the ruling planet of Gemini, so it is at home in this sign and feels comfortable here. You have a lively intellectual curiosity, which can sometimes lead to mental restlessness. You have a playful nature and may tease others or mock them; your critical mind can sometimes be a bit provocative. You have a great sense of humor and often practice self-deprecation. Very sociable and often talkative, you are gifted at expressing yourself and communicating, even bluffing or lying a little when it suits you.

Mercury in Cancer

Your mind is dreamy, imaginative, contemplative, and meditative, and you likely have a good memory. Sometimes, overwhelming emotions prevent you from concentrating. You are passionate about everything related to the past, history, and roots. In your relationships, you need to feel in sync with others' thoughts; otherwise, you remain on the defensive.

Mercury in Leo

Your mind is quite concrete and often generous. You get straight to the point and have a knack for synthesis. You seek intellectual growth and are always on the lookout for ideas and trends around you that can enhance your value. You have a certain power of persuasion and a strong will to understand and learn more. Depending on the rest of your natal chart, you may be domineering, lack humility, or, on the contrary, use your brilliant mind to serve a noble cause.

Mercury in Virgo

Mercury is also the ruling planet of Virgo (as it is for Gemini). It is very comfortable in this sign. However, since Virgo is an Earth sign rather than an Air sign, Mercury expresses itself in a more cerebral, serious, wise, and introverted way. Mercury in Virgo highlights a talent for written expression and is more introspective compared to Mercury in Gemini, which is outward-focused. You are skilled at organization, and your mind is methodical, needing order around you. In your analyses, you delve into detail and can solve problems better than others thanks to your patience and discernment. Critical, especially self-critical, you may lack self-confidence, doubt yourself, and never feel like you've achieved the perfection you dream of. You may possess great mental sharpness or be very skilled with your hands.

Mercury in Libra

Your mind is charming, diplomatic, and nuanced. You dislike taking overly categorical positions. Your intelligence is refined and selective, and you don't clutter yourself with unnecessary details. Your love for compromise makes you sociable, but you don't lack critical thinking. Depending on the rest of your chart, you may, on the negative side, be too hesitant and indecisive or easily influenced by others.

Mercury in Scorpio

Your mind is sharp, quick, and instinctive. You are highly curious, eager to learn, experiment, and delve deeply into subjects. Often provocative and non-conformist, you struggle with making concessions. You are not afraid of controversy. This can be exciting, unless, depending on the rest of your chart, you limit yourself to petty arguments. Your psychological insight and strategic thinking may lead you to dominate those around you, whether intentionally or not. You detest unspoken truths and human hypocrisy, and in response, your rebellious mind can become aggressive. Investigations and mysteries fascinate you. Your strong intuition may even give you premonitory abilities.

Mercury in Sagittarius

Your synthetic mind is open, generous, and full of goodwill. You advocate for tolerance and avoid complications. In fact, you have a knack for simplifying things. You seek to broaden your cultural, social, and geographical horizons. Discovery excites you. Optimistic and extroverted, you bring good cheer to those around you. Depending on the rest of your chart, your desire to maintain others' favor may lead to confusion: you may become too naive and be taken advantage of, or you may resort to hypocrisy.

Mercury in Capricorn

You are likely quite reserved and cautious. Your mind is guided by reason, primarily logical and practical. You dislike approximations, and your approach is somewhat scientific, basing your arguments on what is verifiable and quantifiable. Sciences, mathematics, and history with its precise dates likely attract you. Your seriousness, perseverance, and concentration can take you far in your studies. Your unshakable convictions impress others and may even lead you into politics. Of course, all of this depends on the rest of your chart. Avoid falling into intransigence, coldness, skepticism, or pessimism. Don’t forget to embrace humor and spontaneity!

Mercury in Aquarius

Your mind is inventive, curious, flexible, and dynamic. You often stand out with your ideas and your outlook on life. You advocate for freedom of thought, which may lead you to campaign for tolerance and diversity. Depending on the rest of your chart, you may be passionate about humanity, psychology, and how people live, or you may be more focused on cutting-edge technologies, computing, aeronautics, etc.

Mercury in Pisces

Your mind is primarily intuitive and inspired, absorbing your environment and letting information flow in rather than analyzing things through a logical process. You pick up on things and feel them rather than analyze them. This can give you a rich imagination, impressive intuition, or even premonitory abilities. However, it can also lead to confusion, irrational fears, anxiety, melancholy, and illusions.

The influence of Mercury according to its position in the Astrological Houses

💡 Before you start reading, do you know what an astrological house is and why it’s important? No? Then this article is for you: Astrological houses: What role do they play? What do they mean?

Mercury in the 1st House

Curious about everything, flexible, and adaptable, you seek to understand and analyze. Your quick mind is not without humor. You often see life from a positive perspective. You are very talkative and skilled at communication and exchanges. You need variety; otherwise, you quickly get bored. Depending on the rest of your chart, this Mercurial position may make you nervous, unstable, and scattered.

Mercury in the 2nd House

You have a knack for making the most of your natural environment, and your resourcefulness allows you to satisfy your desires with the tools you have at hand. Clever, you can earn money through various activities and your great ability to adapt to circumstances. You know how to profit better than others, even if, depending on the rest of your chart, you may spend your wealth. Transactions can become a game. The key is not to fall into manipulation or become obsessed with money.

Mercury in the 3rd House

You have a great need for expression, whether verbal, written, or physical, and you are skilled at it. Talkative and curious, you are always seeking to expand your knowledge. You enjoy teaching, playing the role of mediator or educator, and maintaining constant contact with others. If Mercury receives negative aspects, this position may lead to unhealthy curiosity and gossip.

Mercury in the 4th House

This position of Mercury may indicate that you were intellectually stimulated during your childhood, within your family, or in your natural environment. As a result, you likely strive to establish a similar atmosphere in your own home, fostering communication, intellectual growth, and mental development. You enjoy having people over, welcoming new encounters, or engaging in diverse discussions. If Mercury is poorly aspected, this position may instead represent relational difficulties with parents, siblings, or family members.

Mercury in the 5th House

Mercury in the house of vitality can indicate ups and downs related to nervousness and energy depletion... This house is also associated with pleasures and love. With Mercury here, you may intellectualize your feelings, flitting from one relationship to another for fun... Relationships with children and teenagers are favored, and you may become an excellent teacher. You may also express various talents through art. Games, distractions, and leisure activities are also areas of interest for you.

Mercury in the 6th House

Mercury, a very skilled planet, in the house of work and daily life, enhances your methodical mind, and you excel in the practical aspects of things. In material matters, it’s the same—you leave nothing to chance. However, when a sector doesn’t interest you, you may neglect it. Depending on the rest of your chart, this Mercurial position may indicate that you are too perfectionistic and (self-)critical. Try to relax so as not to stress yourself unnecessarily.

Mercury in the 7th House

Mercury, the planet of communication, is here in the house of partnership and associations. You need to share your ideas and establish exchanges with many people. To do this, you often create friendly relationships and seek to live in harmony with others. You are generally tolerant. In your union, you seek intellectual exchange and conversation; otherwise, you get bored. With everyone, you know how to find compromises.

Mercury in the 8th House

Your thoughts and mind are in constant evolution. You need to study secrets, psychology, the cycle of life and death, and sexuality... Sometimes, the irrational attracts you, but only so you can analyze phenomena in a Cartesian way without blindly believing everything. You are particularly skilled at finding practical solutions in crises, recovering from setbacks, and adapting to life’s challenges.

Mercury in the 9th House

You have high aspirations (diverse and in-depth studies) and intellectual ambition. You may also be on a religious or spiritual quest or dedicate yourself to a noble cause. The 9th house is also the house of travel and foreign lands: you may use your intellectual curiosity to broaden your social and geographical horizons... For this, you should easily adapt to different mentalities.

Mercury in the 10th House

Mercury in the house of ambitions and professional achievements may simply indicate ease in working in communication or commerce. You could also wear multiple hats and thrive in different professions simultaneously. You are skilled at expression, and your eloquence helps you get what you want. On the negative side, you may struggle to find direction due to having many talents and may spread yourself too thin. Of course, this depends on the sign in which Mercury is located and the aspects it receives.

Mercury in the 11th House

This position of Mercury makes you someone with an original, independent mind, who may become self-taught. Depending on how Mercury is aspected, you may also be undisciplined, rebellious, or enjoy contradicting others... In friendship, you seek intelligence, humor, and subtle minds in those close to you. You tend to take on too many projects at once but may not always see them through... (this depends on the aspects and the sign in which Mercury is located).

Mercury in the 12th House

Mercury, the planet of thought, is here in the house of infinity, but it’s also the planet of communication in the house of limits. You may be taciturn, spending hours reflecting on your own. For you, there are no limits to how deeply you can explore a subject. You may often feel tempted to isolate yourself to meditate, pray, or study... This aspect may indicate that, in the face of significant life challenges, you remain clear-headed and composed, or, on the contrary, depending on the sign in which Mercury is located and the aspects it receives, you may be overwhelmed by emotions and completely lose your way.

Mercury in Astronomy: The First Planet of the Solar System

The first planet of the solar system is Mercury, located at an average distance of 58 million kilometers from the Sun. The planet’s orbit is a rather flattened ellipse, so the distance varies greatly. Mercury’s rotation around the Sun takes 88 days. With a diameter of 4,900 kilometers, Mercury is the smallest planet in the solar system (Pluto is now considered a dwarf planet). Its mass and gravity are low. It is a rocky planet with almost no atmosphere.

Mercury in Mythology: The Messenger of the Gods

In Egypt, people believed that the planet Mercury was actually two distinct stars, one appearing in the morning and the other in the evening (in fact, it was Mercury, the same planet!). For them, it represented Set and Horus (hence the Mercurial duality).

According to the Roman adaptation of the Greek legend of Hermes, Mercury is the son of Jupiter and the nymph Maia, daughter of Atlas. Depicted as a slender, agile young man with a winged helmet and wings on his feet, he carries a caduceus given to him by Apollo. Mercury is very fast and quick-witted; he is the messenger of the gods. He symbolizes communication, speech, but also transportation (movement, travel), merchants (and thieves!), as well as intelligence, knowledge, and doctors.
