In addition to the Earth, Astrology deals with ten planets, namely the Sun, the Moon (the two luminaries are considered planets in astrology), Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. Minor celestial bodies, such as the Dark Moon, asteroids, and the nodal axis, are also taken into account and are addressed at the end of this chapter. Each planet has its precise function in the natal chart and represents a specific energy. The planet’s action is influenced by the sign it tenants. It plays out primarily in the area of life indicated by the house where it is posted.
The planets are divided into two classes: personal planets, (or fast-moving planets), and collective planets (or slow-moving planets).
The personal planets are the Sun, the Moon, Mercury, Venus, and Mars. They are said to be fast-moving because it takes them a short time to travel the Zodiacal circle (from a minimum of 28 days for the Moon to a maximum of 1 year and 220 days for Mars). As they quickly shift from one sign to the other, they release their energies very differently in each individual.
The other planets are slower and require between 12 to 249 years to travel through the entire Zodiac, depending on the planet considered. This is the reason why they are called collective planets, with the exception of Jupiter and Saturn, because their motion is faster. Collective planets remain in a sign for several years and their energies affect one or several generations. Therefore, their influence on the individual’s personality is less important.
The Sun and the Moon are two valuable sources of information on the individual’s basic psychology. They are of utmost importance for the interpretation of the natal chart and are called Luminaries because they are the brightest planets.
The Sun takes approximately 365 days to travel through the Zodiac and spends 30 days in each sign. (There are 30 degrees in a sign). The Sun’s daily motion is roughly of one degree. In astrology, as viewed from the Earth, neither the Sun nor the Moon retrogrades. The luminaries, i.e. the Sun and the Moon, are the only “planets” which never move backward on the Zodiac as they perform their endless dance.
Distance from Earth: 150 million km. Mass: 334 000 times the Earth’s.
Fire is his element. His nature is hot and dry. He rules Leo and is in exaltation in Aries. He is in analogy with the heart.
He represents the father, the husband, and the leader. The age of the Sun covers the period from 20 to 40 years, approximately.
Characterology: emotive, secondary, active. He is passionate.
The Sun is the individual’s ego, his aspirations, his inner self and his will, that which he tends to really be, unlike the Ascendant which is the image projected onto others.
The Sun is the masculine part of the personality, the Yang, and as such, he represents all male figures (father, husband, leader, etc.). He provides clues to the image of the Father and men in general, as well as the type of relationship with them, regardless of the gender of the chart’s owner. However, he seems to be more important in men’s chart, since he stands for all masculine and positive values.
