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, 86% lit; the Moon was 371,132 km away.
astronomy-engine - How far Earth has travelled since [EXACT]
64.3 orbits of the Sun — 60,416 million km, that is 78,585 return trips to the Moon; 23,481 rotations of Earth; with the Sun — 466.6 billion km around the Galactic centre, 18 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 298 million km away; today it is 246 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 19, on the decline (78% through the cycle).
SILSO smoothed minima - When the sky repeats [EXACT]
Mars returns to that day’s point of its orbit on April 19, 2028; Jupiter — in 2033; a full moon exactly on this date — June 20, 2035
sidereal periods: Mars 686.98 d, Jupiter 11.862 yr - How far the sky has drifted since [EXACT]
