What is a zodiac?

Well there are long astronomical and astrological explanations to this term but cutting the long story shorter and simplifying things, lets look at it this way...The Earth revolves around the Sun and completes its revolution in 365 days or one year...As Earth orbits the Sun, the Sun appears to move around with the background of the stars as seen from the Earth's orbit creating an imaginary circle on the celestial sphere which also happens to be the projection of the Earth's orbit around the Sun...This imaginary circle is called the "Ecliptic"...Usually the Moon and the planets are not positioned exactly on the ecliptic because they're not located exactly in the same orbit plane as Earth, but lie within several degrees of it & form a sort of another imaginary circle encompassing the entire sky which we call the "Zodiac".The ecliptic runs exactly along the middle of the Zodiac...
The Zodiac is also called the circle of life with 12 divisions of 30 degrees each representing people , animals and numbers in symbolism.Each of these 12 signs consist of 3 constellations or "nakshatras" further consisting of 4 padas or divisions of two nakshatras and one pada of the third nakshatra... 
Each sign of the Zodiac has its own story expressed through mostly symbolism, ruling planet and the energy of the number it corresponds to...Each sign has three constellations or which make its express its underlying energy through three different means...Its important to understand the energies of these signs to relate them to the houses they sit in your horoscope...
