5 articles for "Inclination"

Inclination [Astro*Index]


Motion of a body toward a position in a chart other than its original location.

♦ Orbit ♦ Inclination, Orbital
Inclination [Munkasey M.]

The tilt of the Earth in its orbit. For the Earth, this is measured by the obliquity. The inclination or tilt of another body measured with respect to the Earth's orbit. See also: "Obliquity".

Inclination [DeVore]

(1) Astrologically, the motion of a body toward a position in the horoscope other than the one it held at birth.

(2) Astronomically, the angle at which the orbit of a planet crosses another orbit, particularly the ecliptic. A point in an orbit is reduced to the ecliptic by subtracting from the vector, the cosine of the declination. The inclination of the Moon's orbit to the ecliptic varies from 4°59' to 5°deg;18'. The Earth's orbit is, of course, the Ecliptic, hence the Sun can have no latitude. That it has declination is due to the fact that the ecliptic makes an angle with the celestial equator of approx. 23°5' – which is described, not as inclination but as the obliquity of the ecliptic. For the inclination of the planets v. Nodes of the Planets.

Inclination of Axis [Astro*Index]

The angle between the the spin-axis of a body and a normal to a given reference plane (usually the Ecliptic or Celestial Equator).

See also:
♦ Ecliptic ♦ Celestial Equator
Inclination, Orbital [Astro*Index]


The smaller of the dihedral angles formed by the intersection of the orbital plane of one body with some reference plane (usually the Ecliptic or Celestial Equator). Also, the angle between the normals to these planes. For Binary or Multiple Stars, the reference plane is usually taken as the line of sight.
