planet mercury in the solar system

Mercury is the smallest planet in the solar system, the planet closest to the Sun, and the speediest of all the planets. Mercury's symbol ( ☿ ) represents the head and winged cap of Hermes, the Greek god of commerce and communication. The ancient Greeks associated Mercury with Hermes, the swift messenger of the gods and many of Hermes' myths give greater definition to astrological Mercury. However, at its most basic, Mercury is the distribution of information.

Astrological Mercury

Astrological Mercury represents the transmission and reception of information. It rules the signs of Gemini and Virgo as well as the 3rd and 6th houses. It's the planet of talking, teaching, writing, listening, learning, reading, and observing. Mercury is also your thought processes, the intake of sensory information from both conscious and unconscious sources, analyzing, sorting, and making sense of everything.

Are your ideas well thought out or do you jump the gun and make mistakes? Are you a quick or slow learner? These are the kind of things that your Mercury's sign placement reveals.

When Mercury is Rx in a chart, the mind turns inward. This inner processing of information is anything but superficial. Mercury Rx in your chart, regardless of it sign placement, frees you to think independently, imaginatively, and innovatively. However, it also reveals some difficulty in self-expression; words do not form and the person feels inarticulate and struggles to make themselves understood.

A Different Kind of Mercurial Make-Up

If your Mercury is retrograde, knowing how it can affect you will help you accept that there's nothing wrong with you, you simply have a different kind of mercurial make-up than others. That understanding can lessen the frustrations you feel when you're unable to get the words out or make yourself understood. About 25 percent of the people on earth have Mercury Rx in their birth chart. To find out if your Mercury is retrograde, you'll need to have your birth chart (see above) and look for the Mercury's glyph (☿). If it has an Rx next to it, you were born when Mercury was retrograde.

Meeting Mercury First

If you meet someone for the first time in person, the first thing you "meet" is their rising sign and when you start talking to them your Mercurys "meet." However, in today's world, you often connect with people the first time by email, Facebook, Twitter, etc. and more and more individuals are searching for a significant other online. This means a lot of people "meet" your Mercury first. Understanding the strengths and weaknesses of your Mercury placement and the aspects it makes to everything else in your horoscope can help you make friends and influence people. Which means that understanding the complexities of your Mercury is definitely worth a consultation with a professional astrologer.
