From the pre-historic times, humankind has been fascinated by the stars and planets. As time passed, we observed that these planets and stars are in constant movement. What we also noticed was that some groups of stars were in a particular formation that corresponded to a particular picture. These groups of stars are called constellations. There are thousands of such constellations in the sky. Generally, it was noted that the Sun stayed in one constellation for the period of one month. The sky above us forms a kind of a circle, which is 360 degrees. The sun moves from constellation to constellation over a period of a month, which means it travels 30 degrees every month to complete this circle. Thus, there are 12 divisions of the sky. The constellations in the sky which correspond to this movement are the 12 constellations―these are called the 12 signs of the zodiac. The Elements and Personality Your zodiac sign gives a glimpse of your inherent personality. This does not mean, for example, that all the Aries people in the world are alike and so on. It just means that certain character traits are common to almost all the Aries people. Each of these signs is also classified into one of the four elements. These four elements and their corresponding signs are:

FIRE	AIR	WATER	EARTH
Aries	Gemini	Cancer	Taurus
Leo	Libra	Scorpio	Virgo
Sagittarius	Aquarius	Pisces	Capricorn

Fire sign people are usually very passionate, energetic, creative, and aggressive. Air sign people are thinkers, idea originators, and truth seekers. Water signs are emotional, creative, and intuitive. Earth signs are sensual, hard-working, sincere, and practical. The Compatibility The sign of the zodiac to which an individual belongs to gives an idea about the person's nature and personality traits. Therefore, we can assume that certain personality types are more compatible with each other. Using the zodiac signs, we can gain a fair idea of the characteristics of an individual's nature. Thus we can gain an insight into what kind of person he/she will best get along with, based on the sun signs compatible with each other. Trends From this list you can observe a few trends. Fire signs are compatible with other fire signs, and Air signs. Air signs are compatible with other Air signs, and Fire signs. Water signs are compatible with other Water signs, and Earth signs. Earth signs are compatible with other Earth signs, and Water signs. This translates to―Fire and Air signs being compatible with each other, and Earth and Water signs being compatible with each other. Dependability There are several other factors at play when the compatibility of two individuals is to be seen, even from an astrological point of view. Two people being compatible with each other, is totally a matter of understanding and maturity. Of course, there is a point where you analyze their astrological charts and find out that either their Moon signs do fall under the rules of this list. Be that as it may, relationships are complex and the interplay of emotions and feelings cannot be summarized in a list. However, some observation does lead you to gaining an understanding of another person's basic character traits and the elemental driving force from within. Sun sign compatibility is not supposed to be a limiting factor in relationships. Instead, zodiac compatibility only aims at creating a better understanding among two individuals. Hopefully, it helps you relate to another on a deeper level, thus helping a relationship gain stability and strength.
