Checkable facts with a tag and a source; the classical reading is in the chart.
- The Moon that day [EXACT]
first quarter, 36% lit; the Moon was 391,173 km away.
astronomy-engine - How far Earth has travelled since [EXACT]
56.6 orbits of the Sun — 53,158 million km, that is 69,144 return trips to the Moon; 20,660 rotations of Earth; with the Sun — 410.6 billion km around the Galactic centre, 15.9 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 311 million km away; today it is 245 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 20, near maximum (48% through the cycle).
