Venus Out of Bounds Dates

Declination is a body's angular distance north or south of the celestial equator, measured in degrees. Unlike zodiac longitude, it is a physical sky coordinate, so it does not depend on house system, tropical vs sidereal zodiac, or any other framing choice. Every chart has both a longitudinal axis and a declination axis.

A planet is out of bounds when its absolute declination exceeds the Sun's own maximum of about 23°26' (the obliquity of the ecliptic at J2000). Moon, Mercury, Venus, Mars, and Pluto can all go OOB; Jupiter, Saturn, Uranus, and Neptune cannot. An OOB body behaves as if it has stepped outside the Sun's envelope and is operating on its own rules.

Two planets are parallel when they share the same declination within a 1° orb (north-north or south-south). Parallels behave as declination-axis conjunctions and often show strong affinity even when no zodiacal aspect is present. Traditional sources including Ptolemy, Kepler, and Sepharial treated parallels as important on their own.

A contraparallel occurs when two planets have equal but opposite declinations (for example +12° and -12°) within a 1° orb. It functions as a declination-axis opposition: the bodies are matched in intensity but poled against each other across the celestial equator.

Jupiter, Saturn, Uranus, and Neptune orbit close to the ecliptic, so they cannot exceed obliquity and never go out of bounds. Pluto is the exception because its orbit is tilted ~17°, which combines with the 23.4° ecliptic tilt to push its declination past 23.4° for roughly one quarter of its 248-year orbit.

No. Declination is a physical equatorial coordinate. It does not depend on Placidus, Whole Sign, Porphyry, Koch, Campanus, Regiomontanus, or any other house system. This makes declination useful when a birth time is uncertain, because house-dependent signals are the first to degrade under time error and declination is not one of them.

No. A contraparallel matches bodies by declination across the celestial equator. An antiscion matches bodies by ecliptic longitude reflected across the Cancer-Capricorn solstice axis. They often point at the same body pairs but they are computed on different axes and carry slightly different meanings.

We compute declinations from NASA's DE440s ephemeris (via the ANISE / JPL toolkit) to arcsecond precision. Out-of-bounds status is flagged at the ±23.4393° J2000 threshold; epoch-of-date obliquity drifts by about 0.013° per century from this value, which is well below the resolution of any traditional OOB claim.
