Checkable facts with a tag and a source; the classical reading is in the chart.
- The Moon that day [EXACT]
new moon, 1% lit; the Moon was 379,958 km away.
astronomy-engine - How far Earth has travelled since [EXACT]
60.4 orbits of the Sun — 56,737 million km, that is 73,799 return trips to the Moon; 22,051 rotations of Earth; with the Sun — 438.2 billion km around the Galactic centre, 16.9 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 371 million km away; today it is 246 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 20, right at the minimum (14% through the cycle).
