Mercury is the closest planet to the Sun in our solar system. It has the shortest and fastest orbit around the Sun. So, it makes sense that it is named for the Roman god that has wings on his heels to give him the extra speed he needs to deliver messages between the gods and the underworld. Mercury is the planet of communication, intelligence, learning, quick thinking, logic, local travel, and siblings. Your Mercury placement in the houses can give you greater insight into how Mercurial energy shows up for you.

Once you’re familiar with the planets and signs, learning more about the houses is a great way to deepen your understanding of astrology. Focusing on the meaning of each planet in a certain house and then examining your own natal chart and those of your friends can help you see the shades of meaning in each planet’s position. You may also begin to notice patterns of those around you. You might begin to notice that you have several friends with similar placements, perhaps ones that are complementary to yours.

What Does Your Mercury Sign Mean?

Mercury is named for the Roman god of the same name. Mercury was the god of communication, especially messages, languages, and commerce. He was also considered a protector of travelers. As the messenger of the gods, he could easily communicate with anyone, and often acted as the middleman in arguments between deities. As previously mentioned, he also had to be speedy, as the divine messenger. The things that the planet rules over harken back to Mercury’s ancient mythological origins.

Your Mercury sign and placement refer to how you communicate, how you learn, and your relationship to quick thinking and intellect. Mercury is also a planet that relates to everyday technology, so it may also give you information about how tech-savvy you are. In our modern era, Mercury is often how we lead when we first meet people, in addition to the rising sign, which is the face we show the world. We often meet people first through digital messaging or e-mail, which is definitely Mercury’s domain.

It can also affect how you learn, how quick-witted you are, and whether you are more logical or more emotional.

People with First House Mercury are often confident communicators but can have nervous energy.

This isn’t because they are self-centered. It’s mainly because they may tend towards social anxiety. They are in their heads a lot and might be thinking about what to say more than what the other person is saying. People with this placement often have a sharp intellect and love learning. They have a lot going on, have tons of energy, and are often overscheduled. They are sometimes more logical than emotional.

People with Mercury in the 2nd House are methodical with their communication. They don’t like to be pushed or prodded into revealing more than they want to. They will open up on their own time. This can result in conflict because some things do require a timely response. However, for the most part, people with this placement are steady and reliable in terms of communication. They think before they speak and thus have the capacity for extra thoughtful and empathetic communication. In terms of learning, they are quite practical and prefer to learn things independently and at their own speed. This can cause difficulty in school because classrooms go at different paces. Mercury 2nd House people may find that they tend to go faster or slower than their classmates, leading to boredom or frustration. Finding ways to learn independently can relieve these feelings.
