At any rate here is my quick primer on the basics of Astrology:

The earthbound sky is divided into 12 equal parts, the 12 signs. of the zodiac. Each sign takes up 30 degrees of the sky and only 6 signs can be seen in the sky at any one time. The other 6 are on the backside of the earth and are visible on the other side. Every 2 hours approximately a new sign pops up on the Eastern horizon and another sign sets on the Western horizon. This is caused by the Earth's rotation. The sign on the Eastern horizon at the time of your birth is your Rising Sign, or Ascendant. It plays an important part in your Astrological profile.

At the time of your birth, the planets of the solar system, including non-planets, Sun and Moon, occupy different areas of the sky. A snapshot of these locations is taken and this represents your Astrological Chart, also known as your Natal Chart. The placement of these planets, as well as the relationship these planets have to one another, influence your personality.
