Checkable facts with a tag and a source; the classical reading is in the chart.
- The Moon that day [EXACT]
new moon, 2% lit; the Moon was 406,534 km away.
astronomy-engine - How far Earth has travelled since [EXACT]
93.3 orbits of the Sun — 87,669 million km, that is 114,034 return trips to the Moon; 34,073 rotations of Earth; with the Sun — 677.1 billion km around the Galactic centre, 26.1 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 205 million km away; today it is 246 million km (farther by 1.2×).
