Mercury: The Messenger of the Gods

Mercury Overview

The planet Mercury is rich in symbolism and mythology. While it’s also commonly referred to in astrology, Mercury is well-studied in science as well. In this post, we’re going to talk about planet Mercury, including what it means to have it in each of the zodiac signs in a natal astrology chart.

Mercury in Science

Mercury, the smallest planet in our solar system. Due to its thin atmosphere, which cannot retain heat, temperatures on the surface can soar to 430° Celsius (800° Fahrenheit) during the day and plummet to -180° Celsius (-290° Fahrenheit) at night. This harsh environment makes it a challenging location for scientific exploration.

Its surface is heavily cratered, resembling the Moon’s. Meanwhile, scientists believe Mercury has undergone significant volcanic activity in the past. It’s also known for its weak magnetic field, which is about 1% as strong as Earth’s. The planet’s orbit is the shortest of any planet in the solar system, taking only 88 Earth days to complete one lap around the Sun.

Symbolism of Mercury

Mercury, aka Hermes, is known in mythology as “the messenger of the gods”. He moves quickly and has a talent for trickery. Much of this comes from his innate ability to communicate.

The mythology of Hermes lines up with our planet, Mercury. This is due to its size and orbital speed. While the symbol for this planet resembles the one used for the planet Venus (♀), it differs because it also contains something similar to horns on its head as seen in the image.

Hermes

Mercury and Venus are the only two planets that rule more than a single sign. Although Gemini and Virgo are quite different, Mercury is multi-faceted and strangely flexible. Therefore, the most obvious commonality between both Gemini and Virgo is the planet Mercury itself, including its characteristics.

Called “the messenger of the gods,” Mercury is an incredibly fast-moving planet! This gives it incomparable speed, nervous energy, and quick-wits. Likewise, this messenger is full of information, curiosity, energy, and intellect.

Mercury Retrograde

It’s like that you’ve heard, “Mercury is in retrograde again,” which it frequently is. However, this is where the planet’s trickery comes into play. During a Mercury retrograde, this planet is known to cause problems.

These difficulties that are often experienced during Mercury retrograde usually include issues with technology and machines. Perhaps your car won’t start, your phone keeps dying, a power line is down, or there seems to be a bug in your favorite game. It can also manifest through difficulties with communication and our ability to express ourselves clearly.

Mercury in Aries

With this placement, you may have a tendency to be somewhat of an aggressive speaker who has no filter. You’re highly opinionated and unafraid to speak your mind and hurt feelings. You might get frustrated easily and lack patience. However, you can also be motivating for others, challenging them to improve themselves.

Mercury in Taurus

You may be prone toward spending a lot of time thinking about your losses and disappointments. Having a stubborn and fixed point of perception, it’s difficult for others to change your mind. Although you can be a patient listener, you don’t give much feedback. Lastly, you have a no-nonsense attitude and a lot of common-sense.

Mercury in Gemini

Having your natal Mercury placement in its sign of rulership means that you express yourself with ease. You have a great sense of humor and people find you playful and lighthearted. Since you’re intelligent, you’re great at puzzles, problem-solving, and simply absorbing information. Lastly, you’re definitely known talking a lot!

Mercury in Cancer

With your natal Mercury in Cancer, you may be more emotional than you are rational. As a result, this could leave you feeling sort of like a wallflower, afraid to open up to more bold personality types. Whenever people speak to you, you’re likelier to remember the emotional impact it had on you rather than their words.

Mercury in Leo

There’s a chance you’ve been called bossy before as your opinions are something you exert in most situations. You might make conversations center around yourself, but you can be quite charming too. Prideful, you take offense to things easily and don’t listen to others when they try to explain. However, you’re super friendly and persuasive.

Mercury in Virgo

Since Mercury is exalted in Virgo, this is a great natal placement to have. You’re highly aware of your surroundings at all times and your mind works rapidly. Being extremely perceptive, you notice almost everything. Lastly, while you are great at communicating, you remain humble due to Virgo’s grounded, earth energy.

Mercury in Libra

When it comes to communicating, you’re the king or queen of passive-aggressive. Since you have a desire for diplomacy in your interactions with others, you find it challenging to be direct. As a result, you might beat around the bush rather than speak up. Unfortunately, this can cause friction in your self-expression.

Mercury in Scorpio

With natal Mercury in Scorpio, you may enjoy talking about things that hide below the surface. Your energy can be intense, but you peak under the hood of every word spoken, looking for deeper meanings. Meanwhile, you’re great investigating and finding information that is not well-known by others.

Mercury in Sagittarius

Whenever natal Mercury is in Sagittarius, it’s in detriment. This means that there may be some tension in the way you communicate. You may be rude and overly-opinionated or feel that you’re frequently misunderstood when you speak due to your idealism. There’s a challenge in this placement to discern why you struggle in this area of life.

Mercury in Capricorn

Unlikely to be the most talkative person in the room, you’re highly selective about the words you say. Sometimes you come across as being too serious and other times you enjoy telling dark jokes. Having a skeptical mind, you dislike wasting your time on small talk and meaningless modes of expression.

Mercury in Aquarius

If you have your natal Mercury in the sign of Aquarius, you’re likely an intriguing person to talk to. While have some strange interests, you’re intellectual and quirky. You probably enjoy debating others and asserting your humanitarian point of view. However, you may lack focus and find it challenging to pay attention to others.

Mercury in Pisces

Having your natal Mercury in Pisces means that this placement is in the fall debilitation. As such, you may seriously struggle to express yourself authentically. Communicating feels like a lot of pressure for you. Therefore, you prefer to spend your thoughts within your dreams, isolated. Having to chit-chat quickly overwhelms you.
