Kepler coined "perihelium" as latin for "point of an orbit closest to the sun" and published it his 1609 book "Astronomia nova aitiologetos", so insisting on 1680 because that's when the spelling with "on" at the end arose is some real pedantic quibbling.
Surely it's more tempting to go for "it should be 415" is more tempting?
According to my etymology source, perihelion came out in the 1680s, so it's closer to 350 years, not 400
