The 18 pages that link to Precession of the equinoxes, each with the reason it gives.

• HipparchusBroader topic: Hipparchus inferred this long-term shift by comparing stellar observations with earlier records.

• Milankovitch cyclesRelated: It describes the combined precessional shift that changes which season occurs near perihelion.

• Tropical yearBroader topic: Recognition of this motion explains why equinox-based and star-based years differ.

• AstrologyRelated: Precession explains why tropical and sidereal zodiac positions have diverged.

• EquinoxRelated: It shifts equinox positions against the stars and makes the tropical year shorter than the sidereal year.

• ChronologyRelated: Astronomical dating must account for changing celestial alignments across long periods.

• Axial precessionBroader topic: It is the sky-coordinate expression of Earth's changing rotational-axis direction.

• SolsticeRelated: It shifts the seasonal points against the background constellations over millennia.

• Solar yearRelated: It shifts the seasonal reference point relative to the stars and changes the year’s measured length.

• June solsticeRelated: It shifts the solstice’s position against the background stars over long timescales.

• PrecessionBroader topic: It shifts the seasonal reference points against the stars over long periods.

• PosidoniusRelated: Posidonius discussed this astronomical phenomenon, first identified by Hipparchus.

• September equinoxRelated: It gradually changes which constellations lie behind the Sun at this equinox.

• Astronomical tablesRelated: Uncorrected precession gradually made older star and coordinate tables inaccurate.

• Simon NewcombRelated: His constants and tables incorporated this changing reference frame.

• Guo ShoujingRelated: Guo’s astronomical calculations accounted for changing celestial reference points over time.

• Age of AquariusRelated: This astronomical cycle supplies the proposed transitions between astrological ages.

• Astrological signRelated: It explains why tropical signs drift relative to the constellations.
