The Zodiac

Astronomically, the Zodiac refers to the part of the sky that is 8 degrees north and south of the ecliptic, which is the path of the Sun across the celestial sphere from the view of earth over the course of the year. The paths of the Moon and the planets are also within the belt of the zodiac.

Astrologically, the Zodiac refers to the 12 signs that rule each of the 30 degrees that make up the 360 degree “wheel of the sky”.  The start of the astrological Zodiac begins with Aries at 0 degrees, which is the vernal or spring equinox. Aries rules the first 30 degrees, Taurus the second 30, then Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces.

Two Systems of Astrology (Tropical and Sidereal)

There are two primary systems of astrology that make up the bulk of astrological texts, websites, and private consultations.  One is tropical astrology, used extensively in Western culture (the United States and Europe) and the other is sidereal astrology, used extensively in Eastern culture (India) and best known as Vedic astrology.  Askastrology information is based on Tropical astrology.  Below is a succinct explanation of the two and how they differ:

Sidereal and tropical are terms used to describe two different definitions of a year. In astrology, they refer to two different systems of ecliptic coordinates used to divide the ecliptic into twelve “signs”. Each sign is divided into 30 degrees, making a total of 360 degrees.

While sidereal systems of astrology define the signs relative to the apparent backwards movement of fixed stars of about 1 degree every 72 years from the perspective of the Earth, tropical systems fix the vernal point or vernal equinox (also known as the March equinox in the Northern hemisphere) to 0 degrees of Aries and define the rest of the zodiac from this point. Sidereal astrology uses corrective systems known as ayanamsas (Sanskrit: ‘ayana’ “movement” + ‘aṃśa’ “component”) to account for the precession of equinoxes, whereas tropical astrology does not use such measures. This has caused the two systems, which were identical around 2,000 years ago, to drift apart over the centuries.

So, a person born on April 1, 2021 at 12:15 pm in Lynchburg, Virginia would have a Tropical Sun sign of Aries at 12 degrees and 10 minutes.  That same person would a Sidereal Sun sign of 18 degrees and 00 minutes of Pisces. 

House Systems

Tropical astrology divides the wheel of the sky into 12 pie pieces, called houses, which get calculated and determined by time and location on the day of birth.  If the time of birth is unknown an astrologer my choose to use 12 am or 12 pm and provide interpretations based solely on the position of the points in signs and in relationship to one another by certain angles, called aspects.  It is possible to attempt find the correct time using a complex process known as rectification, which involves taking significant events from a person’s life and then working backwards to determine which birth time would yield the outcomes from the person’s life events.

Every house system is calculated on the rotational movement of Earth on its axis, but there is a wide range of approaches based on different calculations methods to determine how the houses are demarcated.  Below is a list of the various house systems used in Tropical astrology over its inception and up to the current time:

  • Placidus (most used)
  • Whole Signs
  • Equal Signs
  • Porphyry
  • Regiomontanus
  • Campanus
  • Koch

Regardless of which system used, the position of the points will be in the same signs.

Zodiac Signs: Astrology Qualities, Modalities, and Elements

Other than the four astrology elements (Water, Fire, Earth, and Air), the twelve signs of the Zodiac are also classified through the zodiac qualities. There are three qualities in astrology: Cardinal, Fixed, and Mutable. These qualities are also called Quadruplicities, and they have a significant effect on a person’s general outlook and attitude, and indicate how they function in their daily life. The qualities represent how a person with a certain sign interacts with their environment, how they respond to situations, and how they interact with other people. Every person plays a different role on a team, some are starters or initiators (Cardinal), some are the hard workers (Fixed), and some are the connectors (Mutable).

The twelve houses also have a quadruplicity in their modalities: Angular, Succedent, and Cadent, which correspond to the three qualities.  The first house is Angular and ruled by a Cardinal sign (Aries), the second house is Succedent and ruled by a Fixed sign (Taurus), the third house is Cadent and ruled by a Mutable sign (Gemini), and so on around the wheel.

The Fire and Air signs are Masculine and the Earth and Water signs are Feminine.

13th Astrological Sign

Modern astronomy has recorded 88 constellations covering the southern and northern hemispheres of our sky. 13 of these constellations cross or touch the ecliptic – the trajectory of the Sun’s apparent path across the sky as seen from Earth.

These include the constellations that inspired the names of the 12 Tropical astrology signs, plus a thirteenth constellation – Ophiuchus sign (Oaf-ih-YOU-kus), which was known but not included in the Tropical zodiac.

Is Ophiuchus the 13th Zodiac Sign?

No. In astrological terms, this sign would only be meaningfully significant if Tropical (western) astrology was still tied to the position of the constellations. It is not, and your zodiac sign, also known as your sun sign is one among the twelve most everyone knows.
