The maximum possible declination of the Sun is 23° 28' which occurs at the time of Solstices, when the Sun passes the Tropics (0°) of Cancer and (0°) Capricorn, this is the limit of the pole's greatest inclination from the plane of the Earth's orbit. The first degrees of Aries and Libra have no declination, since at these points the ecliptic intersects the equator. However, planets at this longitude may have declination.
The declination of a body whose longitude and latitude are known is found by this formula:
- Radius (10,000): Tangent of Ecliptic (23° 27'):: sine of longitudinal distance from equinox: tangent of Angle A.
- Cosine of Angle A: cosine (latitude plus/minus 90°- minus Angle A): cosine of Ecliptic Obliquity (23° 27'): sine of the Declination.
The Moon, Mercury, Mars reach a declination of 27° north, and on rare occasions Venus reaches 28°. Jupiter, Saturn, Uranus and Neptune have practically the same declination as the Sun.
Planets transiting in declination are considered to be “out of bounds”, meaning Saturn can not put restriction on the planet, it is in effect unstoppable. Those who have OOB planets in their charts often experience very different lives to others, finding restriction in joining religious groups, marrying into ready made families, but these decisions are made by choice in adults.
