To verify these five periods, below is a scan from Wikipedia:-

In the scan below, Pluto’s “orbital period” (ie:- revolving round Charon, as a binary planet Pluto/Charon) is given as 6.387230 Earth days. In fact, this is Pluto’s ROTATION Period, and Pluto’s ORBITAL (ie:- Revolution) Period is listed as 90803.66 Earth days. (See Section 2 of this appendix – fourth table.).
