My question is a bit more complicated than that, actually. Here's a quote from Vladimir Nabokov's "Lolita":
"Whose cat has scratched poor you?" A full-blown fleshy handsome woman of the repulsive type to which I was particularly attractive might ask me at the "lodge," during a table d'hote dinner followed by dancing promised to Lo. This was one of the reasons why I tried to keep as far away from people as possible, while Lo, on the other hand, would do her utmost to draw as many potential witnesses into her orbit as she could.
Was it before or after "orbit" became a popular astronomical term? (I.e. before or after Kepler?)
