Horoscope or other commonly used names for the horoscope in English include natal chart

Placements of the planets[edit]

Main article: Planets in astrology

Having established the relative positions of the signs in the houses, the astrologer positions the sun, moon, and planets at their proper celestial longitudes. Some astrologers also take note of minor planetary bodies, fixed stars, asteroids (for example, Chiron) and other mathematically calculated points and angles such as the vertex, equatorial ascendant, etc. Many astrologers also use what are commonly referred to as Arabic parts (or Greek Lots), the most common of which is the Part of Fortune (Pars Fortunae).

Aspects[edit]

To complete the horoscope the astrologer will consider the aspects or relative angles between pairs of planets. More exact aspects are considered more important. The difference between the exact aspect and the actual aspect is called the orb. Those generally recognized by the astrological community are Conjunction (0°), Opposition (180°), Square (90°), Trine (120°), Sextile (60°), Semi-Square (45°), Sesquisquare (135°), and Quincunx (150°). Understandably these aspects are more significant when they are exact, but they are considered to function within an orb of influence, the size of which varies according to the importance of each aspect. Thus conjunctions are believed to operate with a larger orb than sextiles. Most modern astrologers use an orb of 8° or less for aspects involving the Sun, Moon, and Jupiter and smaller orbs for the other points. Some astrologers, such as practitioners of Cosmobiology, and Uranian astrology, use minor aspects (15°, 22.5°, 67.5°, 72°, 75°, 105°, 112.5°, 157.5°, 165°) with much narrower orbs.

The major astrological system regarded universally is Vedic Hindu Astrology. As per this, all planets see just opposite i.e. 180 degree aspect. But Mars, Jupiter, and Saturn have special aspects. Mars sees the houses 4th and 8 too from its place in the horoscope, Saturn sees the houses 3 and 10 too from its place, and Jupiter sees 5 and 9 from its place in the horoscope i.e. the house in which they are posited in the lagna chart.

Ascendant[edit]

The ascendant (ASC) is a point on the ecliptic that rises on the eastern horizon at sunrise and changes as the earth rotates on its axis. The ascendant is very important in astrological chart interpretation. It exerts more power than the sun, moon and planets because it infiltrates everything in the natal chart. The ascendant is the first point of energy in the natal chart and it represents the way we view life. The sign on the ascendant characterises our expression of "who we are" when dealing with others, and our initial action when dealing with day-to-day concerns. Longitude is necessary in order to determine the position of the Ascendant because horoscopes use local time. Having constructed the horoscope, the astrologer can begin the task of interpreting the chart. This interpretation depends upon which branch of horoscopic astrology is being used.

Chinese horoscopes[edit]

The 12 Chinese zodiac animals

In Chinese astrology, horoscopes are based on the symbolism of the Chinese zodiac, a system of elements and animals associated with each year according to a Sexagenary cycle. Chinese horoscopes often appear in horoscope sections in newspapers and magazine alongside Western horoscopes.

Criticism[edit]

Interest in horoscopes and the zodiac sign have been very popular throughout history and today. There are many faithful followers, from celebrities to the general public. With so many believers, and perhaps a personal connection to the horoscope or the zodiac, it can be difficult to accept that astrology is not grounded in scientific evidence and is a pseudoscience.
