the moving pole

LITEarth's axis precesses once in about 26,000 years, so J2000 coordinates must be precessed to date, which every professional chart and ephemeris does. Polaris comes closest to the pole around 2100. Vega was near the pole around 12,000 BCE and will be again around 13,700 CE. Over such long spans the IAU 1976 polynomial used here is only approximate (MODEL beyond about ±5,000 yr).

COMPUTEDCross-link to Kyoto blossom: the page computes the Sun's ecliptic longitude on 2021-03-26 (the earliest bloom) from the ephemeris. It is just past the equinox.
