This question resolves as "YES" if a spacecraft acheives a stable orbit within the Hill Sphere of a star other than the sun prior to January 1st 2200. Merely passing through the Hill Sphere without decelerating into orbit, as with the Breakthough Starshot and Daedalus proposed interstellar missions, does not count. The spacecraft must be built by human civilization or a descendant - detecting an alien spacecraft in another star system would not qualify.
