Checkable facts with a tag and a source; the classical reading is in the chart.
- The Moon that day [EXACT]
last quarter, 61% lit; the Moon was 378,283 km away.
astronomy-engine - How far Earth has travelled since [EXACT]
44.1 orbits of the Sun — 41,490 million km, that is 53,967 return trips to the Moon; 16,125 rotations of Earth; with the Sun — 320.4 billion km around the Galactic centre, 12.4 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 203 million km away; today it is 245 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 21, on the decline (61% through the cycle).
