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.

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.

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.

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.

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.

However, it can also lead to confusion, irrational fears, anxiety, melancholy, and illusions.

👉 Be cautious when Mercury is Retrograde, as nothing goes as planned! Be prepared.

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.
