What influence does Mercury have on astrology? What effects?

Mercury in astrology: the intellect

This so-called "fast" planet represents in a birth chart our mind, our intellect, our way of thinking, our ease of learning or not, our way of analyzing. It's a cerebral planet of reflection and expression. It can give clues about our way of speaking, writing, moving. It can also symbolize finances, business dealings, it's also our son (if we have one), our brother, our friend, the adolescence we experienced.

In astrology, a planet can exert a positive or negative influence, depending on its position and movement, whether it's retrograde or not. In positive influence Mercury brings the best of its capacities, otherwise it exerts 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: casualness, superficiality, lack of will, gossiping, insensitivity, scattering, duplicity, instability, trickery, nervousness...
  • On a symbolic level: Mercury represents: curiosity, association, meetings, money, studies, analysis, logic, sorting, medicine, lawyer, writer, brother, son...

Mercury in astrological signs: what influence?

Where is Mercury located in your birth chart? Its position in this or that astrological sign has an influence, discover which one.

Mercury in Aries

Your mind is inventive, bold, your ideas spring forth one after another. Generally, once you've thought of something, you apply it very quickly. You're a person of action, of conviction. However, you may lack concentration and multiply centers of interest, at the risk of scattering yourself and not deepening your reflection. When you express yourself, you don't beat around the bush. Your spontaneity and frankness can hurt.

Mercury in Taurus

You think a lot before acting, you avoid betting on chance, improvising. You rely more on your sense of analysis than on your intuition. You have a practical, realistic mind, anchored in material reality. You take the time to study the ins and outs of a situation, you deepen your knowledge: all this can delay you. However, you know how to organize, manage, concentrate on an objective, see your ideas through to their realization. On the negative side, you can show stubbornness to the point of closing yourself off to other solutions, to others' proposals, etc.

Mercury in Gemini

Mercury is the ruling planet of Gemini, so it's at home in this sign, it's comfortable there. You possess a lively intellectual curiosity, which can sometimes go as far as a certain mental agitation. You have a taste for games, you can thus tease others, mock: your critical mind is sometimes a bit provocative. You possess a lot of humor and often practice self-deprecation. Very sociable, often talkative, you're gifted at expressing yourself, at communicating, even to the point of bluffing or lying a little when it suits you.

Mercury in Cancer

Your mind is dreamy, imaginative, contemplative, meditative, you certainly possess a good memory. Sometimes, your overwhelming emotions prevent you from concentrating. Everything concerning the past, History, roots fascinates you. In your relationships, you need to feel in osmosis of thought with others otherwise you remain defensive.

Mercury in Leo

Your mind is quite concrete and often generous. You go straight to the point and possess a sense of synthesis. You seek to elevate yourself intellectually and for this, you're always on the lookout for ideas, currents around you that can enhance you. You have a certain power of conviction, a lot of will to understand and know more. Depending on the rest of your birth chart, you can prove domineering, lack humility or on the contrary, put your brilliant mind at the service of a noble cause.

Mercury in Virgo

Mercury is also the ruling planet of Virgo (as for Gemini). It's therefore very comfortable in this sign. But here, as it's an Earth sign and not Air, it will express itself in a more cerebral, more serious, wiser, more introverted manner. Mercury in Virgo highlights a talent for written expression, it's more withdrawn compared to Mercury in Gemini which is turned towards others. You're gifted for organization, your mind is methodical, you need order around you. In your analyses, you go into detail, you can solve problems better than others thanks to your patience, your discernment abilities. Critical and especially self-critical, you can however lack self-confidence, doubt yourself, never reach that perfection you dream of. You can show great finesse of mind or even be very skillful with your hands.

Mercury in Libra

Your mind is charming, diplomatic, nuanced. You hate overly categorical positions. Your intelligence is refined, selective, you don't burden yourself with superfluity. Your taste for compromise makes you sociable but you don't lack critical sense for all that. Depending on the rest of the chart, you can, on the negative side, show yourself too hesitant and indecisive or let yourself be influenced by others.

Mercury in Scorpio

Your mind is perceptive, quick and instinctive. Your curiosity is keen, you thirst to know, to experiment, to deepen your subjects. Often provocative and nonconformist, you struggle with concessions. You don't fear controversy. This can be fascinating, unless, depending on the rest of your chart, you limit yourself to quibbling. Your psychological sense and your fine strategy can push you to dominate your surroundings, voluntarily or not. You hate the unspoken, human comedy and faced with this, your rebellious mind can become aggressive. Investigations, enigmas fascinate you. Your strong intuition can go as far as premonitory gifts.

Mercury in Sagittarius

Your synthetic mind is open, generous and full of good will. You advocate tolerance and flee complication. Besides, you have the art of simplifying things. You seek to broaden your cultural, social, geographical horizon. Discovery animates you. Optimistic and extroverted, you spread good humor around. Depending on the rest of your chart, your desire to keep others' sympathy can lead you to a certain confusion: making you too naive and getting taken advantage of or pushing you to hypocrisy.

Mercury in Capricorn

You're certainly quite reserved and circumspect. Your mind is guided by reason, it's above all logical, concrete. You hate approximations, your approach has something scientific about it, you base your arguments on what's verifiable, quantifiable etc. Sciences, mathematics, history with its precise dates: all this certainly attracts you. Your seriousness, your perseverance, your concentration can take you far in studies. Your unshakeable convictions impress and can even lead you to politics. Of course, all this depends on the rest of your chart. Avoid falling into intransigence, coldness, skepticism, pessimism. Don't forget humor and fantasy!

Mercury in Aquarius

Your mind is inventive, curious, flexible and dynamic. You often distinguish yourself by your ideas and your conception of existence. You advocate freedom of thought, which can lead you to campaign to defend tolerance and difference. Depending on the rest of your chart, you can be passionate about humanity, about the psychology of beings, their way of life or you're rather turned towards cutting-edge techniques, computing, aeronautics, etc.

Mercury in Pisces

Your mind is above all intuitive and inspired, it imbibes its environment, lets itself be penetrated by information rather than seeking to analyze things through a logical approach. You capture, you feel rather than analyze. This can offer you a teeming imagination, amazing intuition, even premonitory gifts. However, this can also lead you into confusion, irrational fears, anxieties, melancholy, illusions, etc.

As a result, you probably want to establish in your own home this ease of communication, this need to enrich yourself intellectually, to work on your intelligence. You like having people at home, welcoming new encounters or having varied discussions. If Mercury is badly aspected, this position can represent on the contrary relational difficulties with parents, brothers and sisters.

Mercury in house 6

Mercury, very skillful star, in the House of work and daily life favors your methodical mind, you excel in the practical aspect of things. In the material domain, it's the same, you leave nothing to chance. However, when a sector doesn't interest you, you can neglect it. Depending on the rest of your birth chart, this Mercurial position can indicate that you're too perfectionist and (self)critical. Try then to relax so as not to stress yourself unnecessarily.

Mercury in house 7

Mercury, star of communication, is located here in the House of couples, associations. You need to share your ideas, to establish exchanges with many people.

This aspect can indicate that faced with important trials of existence, you keep lucidity, composure or on the contrary, depending on the sign where Mercury is located and the aspects it receives, you can be overwhelmed by emotions and totally lose your bearings.

Mercury in astronomy: the first planet of the solar system

The first planet of the solar system is Mercury, which is at an average distance of 58 million kilometers from the Sun. The planet's orbit is a fairly flattened ellipse, so the distance is very variable. Mercury's rotation around the Sun is 88 days. With a diameter of 4900 kilometers, Mercury is the smallest planet in the solar system (Pluto is considered a dwarf planet). Its mass and gravity are low. It's a hard-surface planet that has almost no atmosphere.

Mercury in mythology: the messenger of the gods

In Egypt, they thought that the planet Mercury was actually two distinct stars, one appearing in the morning and the other in the evening (in fact it was indeed Mercury, the same planet!) For them, it was Set and Horus (hence comes Mercury's 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. Represented as a slender, supple young man, with a winged helmet and wings on his feet, he holds a caduceus that Apollo gave him. Mercury is very fast and lively, he's the messenger of the gods. He symbolizes exchanges, communication, speech but also transport (movement, travel), merchants (and thieves!) but also intelligence, knowledge, doctors.
