The Houses wheel is based on the ecliptic (the apparent path of the Sun around the Earth). Each slice (each House) in that circle represents a different area and specific function of your life.
Next, the circle on the right represents the 12 Houses, or areas of your life. The Moon and the rest of the planets also fit into the zodiac wheel, at the point that corresponds to their astronomical position (which we find in an ephemeris). Each section measures 30°, with the whole circle measuring 360°. The zodiac wheel represents our view of the heavens sliced into 12 sections. The Sun spends about one month in each sign, as it travels towards the next sign. From our viewpoint on Earth, the Sun appears to travel around the Earth, passing through each of the 12 zodiac signs. We know that, in actuality, the planets revolve around the Sun, but astrology studies how the solar system interplays with us here on Earth. In your personal horoscope (your natal chart), that inner circle represents the coordinates, or exact location, of your birth place. The inner circle there represents the Earth. The 12 slices represent the 12 signs of the zodiac.
It begins with two circles, each divided into 12 slices. In this lesson you will learn the parts of an astrology birth chart wheel. If you prefer, get your free birth chart instead.)
