I read all the comments in the times post and no one mentions that this is due to the motion of the Artemis II. On the moon there is no "earthrise" or "earthset", only a yearly wobble. On the earth the moon rises and sets because of the earth's rotation. I guess the editors of the NYT knew this so that they put the "earthset" in quotes.
It looks like they chose to use the "universal gravitational constant" "k" instead of Newton^s constant, "G": p.23, "k^2 = universal gravitational constant, 1.32452139x10^20, m^3/(sec^2)(sun mass units)"
But the value and unit of "k" given in the Wikipedia page is different. Do you know what NASA document means by "universal gravitational constant" in modern sense?
