waxing crescent, 31% lit; the Moon was 367,576 km away.
astronomy-engine - How far Earth has travelled since [EXACT]
70.4 orbits of the Sun — 66,154 million km, that is 86,048 return trips to the Moon; 25,711 rotations of Earth; with the Sun — 510.9 billion km around the Galactic centre, 19.7 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 140 million km away; today it is 244 million km (farther by 1.7×).
astronomy-engine; checked against JPL Horizons for 2026-09-14 - Solar cycle [ESTIMATE]
