astronomy-engine - How far Earth has travelled since [EXACT]
73 orbits of the Sun — 68,638 million km, that is 89,279 return trips to the Moon; 26,676 rotations of Earth; with the Sun — 530.1 billion km around the Galactic centre, 20.5 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 378 million km away; today it is 245 million km (closer by 1.5×).
