Mercury Astrology Symbol - Characteristics, Planet Energy and More

By Tina Gong


Symbolically represented by Hermes in Greek mythology, the planet Mercury is the messenger of the gods - as well as our personalities and within astrological transits. In astrology, Mercury's movements influence our day to day communication. Within our personalities, it represents our ideas, our intellect and how we communicate and relate with others.

Mercury as a Ruling Planet: Characteristics of Mercury in Astrology 

Mercury is the ruling planet of both Gemini and Virgo. To be ruled by Mercury can mean that you are curious, communicative, and adaptable - but on the negative side, those ruled by this planet can also be indecisive, critical, and filled with nervous and anxious energy. 

Sometimes, Mercury dominant people may be gifted with a biting sarcasm, quick wit and the ability to learn things very quickly. But their intelligence means that they may also be talented at deception.

Gemini, for example, is the sign of communication - they are gifted in being able to express what they are thinking and feeling. Virgo's structured way of processing information is a testament to their talents of analyzing the world.

How Does the Mercury Symbol Affect Personality in the Zodiac? 

As one of the inner planets of the solar system, Mercury orbits the sun in a much faster rate - meaning that the impact it has on our lives is short term and fleeting. Mercury reflects your communication style as well as how you conceptualize ideas - how you organize, analyze and make sense of the world around you. 

The first impressions we get from others are most likely dictated not by their sun or moon sign, but their Mercury sign. Mercury dictates whether their emails and texts are worded bluntly and to the point - or if they are more polite and friendly. They reveal how we choose our words and the tone that we instinctively take.

Mercury answers the following questions about you:

How do I express yourself? What first impressions do I make? How do I process ideas and information?

    Thanks for this article. I have Mercury at 24 of Cancer in my natal chart, and I know that’s directly related to the change I feel is coming. Also, I learned from your article that Mercury rules Gemini (my midheaven) and Virgo (my ascendent).
