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 gibbous, 78% lit; the Moon was 396,986 km away.
astronomy-engine - How far Earth has travelled since [EXACT]
56.4 orbits of the Sun — 52,997 million km, that is 68,934 return trips to the Moon; 20,597 rotations of Earth; with the Sun — 409.3 billion km around the Galactic centre, 15.8 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 367 million km away; today it is 243 million km (closer by 1.5×).
astronomy-engine; checked against JPL Horizons for 2026-09-14 - Solar cycle [ESTIMATE]
That day fell in solar cycle 20, near maximum (49% through the cycle).
SILSO smoothed minima - When the sky repeats [EXACT]
Mars returns to that day’s point of its orbit on October 18, 2026; Jupiter — in 2029; a full moon exactly on this date — May 16, 2041
sidereal periods: Mars 686.98 d, Jupiter 11.862 yr - How far the sky has drifted since [EXACT]
The vernal point has shifted 2,808″ since that day; the real constellations now sit 23.5° away from the astrologers’ “signs”.
