Ascendant (ASC): The leftmost part of a chart wheel, indicating the sign and degree of the Eastern horizon. This sign of the ascendant is
also known as the Rising Sign. This is one of the four angles of a chart wheel, which are considered sensitive points.
Aspect: The angular separation between two bodies, measured along a circle of 360 degrees. The most used aspects are set at increments of 30
degrees (30, 60, 90, 120, 150 and 180 degrees). The different aspects describe ways in which the energies of the two bodies will interact with
each other. Learn more about aspects here.
Astrocartography: (called "Astrogeography" in Europe in earlier years) is one of several methods of Locational Astrology, which purports to
identify varying life conditions through differences in location.
Astrological Chart: Any chart calculated for a specific time and place. A Natal chart is calculated for the time and place of a person's birth:
A transiting chart calculates the transiting position of the planets for a specific time and place (such as an specific event). A Progressed chart
calculates the position of the planets at a specific time and place according to the rules of progression.
Composite chart: Composed of the planetary midpoints of two or more horoscopes. Practitioners of astrology commonly construct a
composite chart when two people meet and form a relationship.
Cusp: The dividing point between either zodiac signs or houses. If a person is born 'on the cusp,' it is at a time when the sun is close to the
beginning or close to the end of a zodiac sign. A house cusp is the dividing point between houses, shown as one of the lines, which radiates
out from the center of the chart.
Element: A basic characteristic or organic quality in astrological interpretation given to the signs of the zodiac. The astrological Elements
are: Earth, Air, Water and Fire.
Ephemeris: A table of values that gives the positions of astronomical objects in the sky at a given time or times.
Horary Astrology: The art of interpreting the relationship between cosmic phenomena resulting from the ordered motions of the celestial
bodies, and a thought, situation or event. It deals successfully only with concrete, well-defined queries, and its validity is subject to question
when the particular problem to be analyzed is hazy in the mind of the querent, or ill defined in its presentation to the astrologer.
House: A division of the chart wheel, representing about one-twelfth of the total chart. The setup of the houses in one's chart is determined
by the positions of the Midheaven and Ascendant. From these two points, the rest of the house cusps are calculated. The houses of the chart
represent the twelve main departments of life. The house system is actually a personalized version of the zodiac superimposed over the actual
zodiac. The overlay of the house and signs systems creates a framework of influences unique to each individual.
Midheaven (MC): The topmost point in a chart wheel, also known as the tenth house cusp. In a natal chart, the Midheaven is the point in
the heavens directly overhead at the time of birth. As with the other angles of a chart, the Midheaven is a sensitive point. Transits or
progressions over the Midheaven can indicate major life events.
Modalities: The basic quality of the signs in terms of their movement of energy - Cardinal: Outward movement - Aries, Cancer, Libra and
Capricorn - enterprising or goal-oriented. Fixed: Inward movement - Taurus, Leo, Scorpio and Aquarius - unchanging or unyielding to
outside influences. Mutable: Spiral movement - Gemini, Virgo, Sagittarius and Pisces - adaptable or changeable.
Moon's nodes: A term used to illustrate the axial tilt of the moon, or the direction in which the axis of the moon is pointing. Every rotating
body has a 'wobble.' Much like a spinning top winding down, the axis of the spinning body moves to form a small circle at the north and
south poles. Over an eighteen-year period, the nodes (or north and south poles) make one complete cycle through the signs of the zodiac. The
position of the north node shows where one can receive greatest benefit or where one is most likely to succeed. The position of the south
node reveals innate abilities and tendencies, but also where one can stagnate or be unfulfilled.
Orb: The number of degrees from exact allowed for an aspect. For most planets, an orb of 6 degrees is allowed. For the sun and moon, an
orb of 10
degrees may be allowed.
Polarity: The division of the signs into two groups of opposite energy impulses: Yang (+)(Aries, Gemini, Leo, Libra, Sagittarius) and Yin (-)
(Taurus, Cancer, Virgo, Scorpio)
Progression: A theory of planetary movement, which states that the planets in a person's natal chart move very slowly over a lifetime. A
person still retains his or her natal chart, but the progressed chart is superimposed over the natal to reveal movement which influences major
life events and circumstances. There are two types of progression. In Primary Progression, one degree is added to each planet's natal position
for each year of real time. In Secondary Progression, one day's planetary movement equals one year of real time. Example: If the moon moves
12 degrees per day in real time, by progression, it moves 12 degrees per year.
Retrograde: A planet's seemingly backward movement as seen from the earth. Retrograde is noted in a chart by an "Rx" after the planet, sign,
and degree. The retrograde movement of a planet in natal & transit charts requires special attention.
Returns: When the transiting planet returns to the precise position it was in at the moment of a person's birth.
Ruler: Each sign of the zodiac and each of the twelve houses is associated with a specific planet, this association is called rulership. Every
sign and every house in a chart has a planetary ruler.
Synastry: The branch of astrology that studies relationships by comparing natal horoscopes.
Transiting Planets: Transits refer to the day-to-day positions of the planets. These positions may be superimposed onto the natal chart to
provide information on current happenings or predictions.
Zodiac or zodiac belt: The pathway in the heavens through which the planets pass in their orbits. Because no planet has a declination
greater than eight degrees north or south of the ecliptic, the movements of the planets are restricted to a zone or belt in the sky known as the
Tropical Zodiac: Planetary longitudes are measured against the point in the sky where the Sun is on the first day of spring. This is the
system most used in chart calculation. Sidereal Zodiac: Planetary body is determined by its relationship to the background of fixed stars.
