waning gibbous, 91% lit; the Moon was 400,628 km away.
astronomy-engine - How far Earth has travelled since [EXACT]
86.2 orbits of the Sun — 81,013 million km, that is 105,376 return trips to the Moon; 31,486 rotations of Earth; with the Sun — 625.7 billion km around the Galactic centre, 24.2 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 394 million km away; today it is 245 million km (closer by 1.6×).
