Checkable facts with a tag and a source; the classical reading is in the chart.
- The Moon that day [EXACT]
full moon, 100% lit; the Moon was 404,686 km away.
astronomy-engine - How far Earth has travelled since [EXACT]
69.2 orbits of the Sun — 64,990 million km, that is 84,534 return trips to the Moon; 25,258 rotations of Earth; with the Sun — 501.9 billion km around the Galactic centre, 19.4 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 394 million km away; today it is 244 million km (closer by 1.6×).
astronomy-engine; checked against JPL Horizons for 2026-09-14 - Solar cycle [ESTIMATE]
That day fell in solar cycle 19, on the rise to maximum (32% through the cycle).
