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 gibbous, 80% lit; the Moon was 366,242 km away.
astronomy-engine - How far Earth has travelled since [EXACT]
6.6 orbits of the Sun — 6,166 million km, that is 8,020 return trips to the Moon; 2,396 rotations of Earth; with the Sun — 47.6 billion km around the Galactic centre, 1.8 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 241 million km away; today it is 245 million km (farther by 1×).
astronomy-engine; checked against JPL Horizons for 2026-09-14 - Solar cycle [ESTIMATE]
That day fell in solar cycle 25, 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 September 21, 2027; Jupiter — in 2032; a full moon exactly on this date — March 13, 2055
sidereal periods: Mars 686.98 d, Jupiter 11.862 yr - How far the sky has drifted since [EXACT]
The vernal point has shifted 324″ since that day; the real constellations now sit 24.1° away from the astrologers’ “signs”.
