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]
waxing crescent, 6% lit; the Moon was 368,756 km away.
astronomy-engine - How far Earth has travelled since [EXACT]
41.1 orbits of the Sun — 38,653 million km, that is 50,277 return trips to the Moon; 15,022 rotations of Earth; with the Sun — 298.5 billion km around the Galactic centre, 11.5 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 394 million km away; today it is 245 million km (closer by 1.6×).
astronomy-engine; checked against JPL Horizons for 2026-09-14 - Solar cycle [ESTIMATE]
That day fell in solar cycle 21, on the decline (90% through the cycle).
SILSO smoothed minima - When the sky repeats [EXACT]
Mars returns to that day’s point of its orbit on January 4, 2027; Jupiter — in 2032; a full moon exactly on this date — August 18, 2054
sidereal periods: Mars 686.98 d, Jupiter 11.862 yr - How far the sky has drifted since [EXACT]
The vernal point has shifted 2,052″ since that day; the real constellations now sit 23.7° away from the astrologers’ “signs”.
