The 44 pages that link to Ecliptic, each with the reason it gives.

• HipparchusRelated: Hipparchus measured celestial positions relative to this fundamental circle.

• AlmagestRelated: The treatise measures planetary positions against this fundamental celestial circle.

• AstrolabeRelated: The rete marks the Sun’s path so its seasonal position can be read.

• Orbital inclinationRelated: Solar-system inclinations are often measured relative to this plane.

• AstrologyRelated: The zodiac is conventionally arranged around this apparent solar path.

• EquinoxRelated: The ecliptic intersects the celestial equator at the equinoxes.

• Earth's orbitRelated: Earth's orbital plane defines the ecliptic.

• Solar declinationRelated: The Sun’s position on the ecliptic determines its declination when projected onto the celestial equator.

• Great circleRelated: It is another major great circle used in celestial coordinate systems.

• Lunar phaseRelated: The Moon’s orbit is tilted to the ecliptic, so phase cycles do not usually produce eclipses.

• Precession of the equinoxesRelated: The equinox points move along this great circle as precession proceeds.

• Earth's axial tiltRelated: Earth's tilt is measured relative to the perpendicular to this plane.

• Retrograde motionRelated: Planets' usual eastward drift and retrograde loops are tracked against this sky reference.

• Ancient Greek astronomyRelated: The ecliptic provided a reference line for locating the Sun and describing planetary positions.

• Lunar monthRelated: The Moon’s motion along the ecliptic helps determine when its phase cycle aligns with the Sun.

• Armillary sphereRelated: Its tilted ring shows the path used to explain the seasons and the zodiac.

• Zodiacal lightRelated: The dust cloud's concentration near this plane gives the glow its zodiacal alignment.

• SolsticeRelated: Solstices occur where the Sun’s apparent path reaches its greatest celestial latitude from the equator.

• June solsticeRelated: The Sun reaches its northernmost position relative to the celestial equator along this path.

• March equinoxRelated: Its intersection with the celestial equator defines an equinox.

• Sidereal monthRelated: The reference great circle against which lunar periods and node motion are measured.

• Celestial globeRelated: Its marked path links the globe's star map to the Sun's yearly motion.

• December solsticeRelated: The Sun reaches its southernmost point on the ecliptic at this solstice.

• Lunar theoryRelated: Classical lunar coordinates commonly measure the Moon’s position relative to this plane.

• New moonRelated: The Moon usually passes above or below the Sun because its orbit is tilted to the ecliptic.

• September equinoxRelated: The Sun’s southward intersection with the celestial equator defines this equinox.

• Southern celestial hemisphereRelated: Its path crosses both celestial hemispheres rather than following the equatorial division.

• ZodiacRelated: The zodiac is centered on this apparent path through the sky.

• Naked-eye astronomyRelated: The Sun, Moon, and planets appear near this path, helping organize naked-eye observations.

• Winter solsticeRelated: The Sun’s position along the ecliptic helps define the solstice.

• Harvest MoonRelated: The ecliptic’s shallow angle to the horizon near autumn makes moonrise times shift less.

• Eclipse cycleRelated: Lunar nodes are defined by the Moon's crossings of this plane.

• Age of AquariusRelated: The equinox point shifts along this path as Earth’s axis precesses.

• Astrological signRelated: The zodiac is arranged along this apparent solar path.

• Astronomical nutationRelated: The changing angle between the ecliptic and equator helps set the nutation torques.
