**Angular**[DeVore]

Said of a planet in an angle (q.v.) or in an angular House. The angular Houses bear a correspondence to the Cardinal Signs and planets therein posited are materially strengthened, though whether beneficially or adversely depends upon the nature of the planet itself as also upon the nature of the aspects it receives from other planets in the Scheme.

**Angular Diameter**[Astro*Index]

Observed diameter of a planet, expressed in angular measure. This gives an accurate measure of the relative size of a body. The actual diameter is calculated by trigonometry, using this measure and the distance of the body from the Earth.

**Angular Distance**[Astro*Index]

The system of arc measurement used by astrologers and astronomers to measure objects on the *celestial sphere*. For example, the angular distance of any two planets in a trine aspect is 120° along the *ecliptic*.

**Angular Distance**[Prima]

Also: Angular Separation

The system of measurement by arc used by astrologers and astronomers to measure objects on the celestial sphere. It is the distance between any two bodies or points on a sphere (or along some reference circle, such as the ecliptic, celestial equator, horizon, prime vertical, etc. See: Aspect Types) and is usually measured in degrees, minutes, and seconds of arc. The maximum arc distance is 180°. Angular separat- ions between planets that meet predescribed geo- metric intervals (0°, 45°, 60°, etc.) are termed partile aspects, and are given specific names such as conjunction, semisquare, sextile, etc. For example, the angular distance of any two planets 120° along the ecliptic is termed a trine aspect.

**Angular House**[Astro*Index]

The 1st, 4th, 7th, and 10th houses of the horoscope; sometimes called the cardinal houses.

♦ Cardinal ♦ First House ♦ Fourth House ♦ Seventh House ♦ Tenth House

**Angular House**[Prima]

The angular houses, related in nature to the cardinal signs, are sometimes called the cardinal houses. They are four in number:

1-st House

4-th House

7-th House

10-th House

The angular houses are defined by the ascendant- descendant and midheaven-Imum Coeli axes. Additional strength has traditionally been ascribed to planets in these houses, especially when they are conjunct the actual angles.

Angular houses concern activities that generate energy or provide impetus. They set processes in motion and symbolize primary areas of experience.

**Angular Momentum**[Astro*Index]

The measure of the rotational motion of a celestial body. Angular momentum = mass x radius of turning (squared) x the rotational velocity.

♦ Orbit ♦ Angular Motion ♦ Rotation Period

**Angular Motion**[Munkasey M.]

This term has to do with the rate of circular motionof a body around a point in space. It is the rate of change of the angle between a fixed line and the line joining the moving body to the fixed point. Angular motion is measured in: radians/second.

**Angular Power Factor**[Astro*Index]

Numerical factor introduced by Gary Duncan and Donald Bradley to indicate the (theoretical) relative strength of a planet at a given position with respect to the main angles of a chart (meridian and horizon). The prime vertical longitude (PVL) is used as the argument. The angular power factor (APF) varies between 100% (conjunct a main angle) and 1% (when 45° distant from a main angle).

The angular power factor (APF) may be computed using the formula: APF = 100.0 - 99.0*abs(sin(PVL)) where PVL is prime vertical longitude.

Some selected values are as follows:

PVL | APF | PVL | APF |
---|---|---|---|

000° | 100.0% | 040° | 35.4% |

001° | 98.3% | 045° | 30.0% |

002° | 96.5% | 050° | 24.2% |

003° | 94.8% | 055° | 18.9% |

004° | 93.1% | 060° | 14.3% |

005° | 91.4% | 065° | 10.3% |

010° | 82.8% | 070° | 7.0% |

015° | 74.4% | 075° | 4.4% |

020° | 66.1% | 080° | 2.5% |

030° | 50.5% | 085° | 1.4% |

035° | 43.2% | 090° | 1.0% |

where PVL is prime vertical longitude. | |||

**Angular Separation**[Astro*Index]

The distance between any two bodies or points on a sphere (or along some reference circle, such as: *ecliptic*, *celestial equator*, *horizon*, *prime vertical*, etc.) usually measured in degrees, minutes, and seconds of arc. The maximum arc distance is 180°. Angular separations between planets that meet predescribed intervals (0°, 45°, 60°, etc.) are termed *partile aspect*s, and are given specific names (conjunction, semisquare, sextile, etc.).

**Angular Velocity**[Astro*Index]

*Angular distance* a planet moves per unit of time. Sometimes erroneously called *daily motion* or *travel*, which refers to the angular distance moved.

See also: ♦ Angular Distance ♦ Daily Motion ♦ Travel

**Angular Velocity**[Munkasey M.]

The speed of angular motion. See: "*Angular Motion*".

See also: ♦ Angular Motion

**Angular Velocity**[DeVore]

The angle through which a planet sweeps in a unit of time. Technically, the daily motion of a planet, expressed in degrees and minutes of arc, is its Angular Velocity.
