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, 24% lit; the Moon was 367,553 km away.
astronomy-engine - How far Earth has travelled since [EXACT]
62.5 orbits of the Sun — 58,784 million km, that is 76,461 return trips to the Moon; 22,846 rotations of Earth; with the Sun — 454 billion km around the Galactic centre, 17.5 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 354 million km away; today it is 244 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 19, on the decline (95% through the cycle).
SILSO smoothed minima - When the sky repeats [EXACT]
