Checkable facts with a tag and a source; the classical reading is in the chart.
- The Moon that day [EXACT]
waxing crescent, 12% lit; the Moon was 372,072 km away.
astronomy-engine - How far Earth has travelled since [EXACT]
35.6 orbits of the Sun — 33,411 million km, that is 43,458 return trips to the Moon; 12,985 rotations of Earth; with the Sun — 258 billion km around the Galactic centre, 10 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 210 million km away; today it is 243 million km (farther by 1.2×).
astronomy-engine; checked against JPL Horizons for 2026-09-14 - Solar cycle [ESTIMATE]
That day fell in solar cycle 22, near maximum (46% through the cycle).
