The day’s dossier, from real data
Checkable facts with a tag and a source; the classical reading is in the chart.
- The Moon that day [EXACT]
waning crescent, 15% lit; the Moon was 386,702 km away.
astronomy-engine - How far Earth has travelled since [EXACT]
11.8 orbits of the Sun — 11,087 million km, that is 14,421 return trips to the Moon; 4,309 rotations of Earth; with the Sun — 85.6 billion km around the Galactic centre, 3.3 light-days.
29.78 km/s along the orbit; 230 km/s around the Galactic centre - Mars then and now [EXACT]
On that day Mars was 285 million km away; today it is 245 million km (closer by 1.2×).
astronomy-engine; checked against JPL Horizons for 2026-09-14 - Solar cycle [ESTIMATE]
That day fell in solar cycle 24, near maximum (55% through the cycle).
SILSO smoothed minima - When the sky repeats [EXACT]
Mars returns to that day’s point of its orbit on February 17, 2028; Jupiter — in 2026; a full moon exactly on this date — December 17, 2051
sidereal periods: Mars 686.98 d, Jupiter 11.862 yr - How far the sky has drifted since [EXACT]
The vernal point has shifted 576″ since that day; the real constellations now sit 24.1° away from the astrologers’ “signs”.
