”Originally conceived as the average of Earth's aphelion and perihelion”
https://www.britannica.com/science/astronomical-unit:
”a unit of length effectively equal to the average, or mean, distance between Earth and the Sun”
I wondered whether the two are equal. A bit to my surprise, they are (http://www.farmingdale.edu/faculty/sheldon-gordon/RecentArti...)
(If we take into account that earth moves faster near its perihelion, I think that will break down)
And, nitpick, nowadays, the AU apparently is exactly 149,597,870,700 meters.
