Checkable facts with a tag and a source; the classical reading is in the chart.
- The Moon that day [EXACT]
last quarter, 67% lit; the Moon was 370,902 km away.
astronomy-engine - How far Earth has travelled since [EXACT]
72.2 orbits of the Sun — 67,858 million km, that is 88,265 return trips to the Moon; 26,373 rotations of Earth; with the Sun — 524.1 billion km around the Galactic centre, 20.2 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 68 million km away; today it is 245 million km (farther by 3.6×).
astronomy-engine; checked against JPL Horizons for 2026-09-14 - Solar cycle [ESTIMATE]
That day fell in solar cycle 19, right at the minimum (3% through the cycle).
SILSO smoothed minima - When the sky repeats [EXACT]
Mars returns to that day’s point of its orbit on November 27, 2027; Jupiter — in 2037.
sidereal periods: Mars 686.98 d, Jupiter 11.862 yr - How far the sky has drifted since [EXACT]
The vernal point has shifted 3,636″ since that day; the real constellations now sit 23.2° away from the astrologers’ “signs”.
