The planets in the Solar System can be classified into three groups, based on their energy properties: Active Masculine Group (Yang): Sun, Mars, Jupiter, Pluto. Passive Feminine Group (Yin): Moon, Venus, Saturn, Neptune. Neutral Group (De): Earth, Mercury, Uranus. The Sun and the Moon are both called planets in astrology, and they are referred to as the "luminaries." Of course, in the astronomical sense, we know that these are not planets (the Sun is a star).
