What does a planet mean in a birth chart?+
A planet symbolizes a psychological function or drive. Mercury represents thinking, Venus values and attraction, and Mars action and desire. The zodiac sign shows how it operates, while the house shows where it appears in life.
Why are the Sun and Moon listed as planets in astrology?+
Astrologers call them the luminaries but commonly group them with the planets for interpretation. Astronomically, the Sun is a star and the Moon is Earth's natural satellite.
Which planet is most important?+
The Sun, Moon, and rising sign are useful starting points, but every planet, house, and aspect contributes to the complete birth chart.
What is a ruling planet?+
Every zodiac sign has a ruling planet. The ruler of your rising sign is often called the chart ruler because its placement offers an important clue about your overall direction.
