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, 6% lit; the Moon was 365,579 km away.
astronomy-engine - How far Earth has travelled since [EXACT]
33.2 orbits of the Sun — 31,205 million km, that is 40,590 return trips to the Moon; 12,128 rotations of Earth; with the Sun — 241 billion km around the Galactic centre, 9.3 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 318 million km away; today it is 246 million km (closer by 1.3×).
astronomy-engine; checked against JPL Horizons for 2026-09-14 - Solar cycle [ESTIMATE]
That day fell in solar cycle 22, on the decline (69% through the cycle).
