Pluto and Charon tidally locked

  • Anonymous - 2013-11-24

    Pluto and Charon should be tidally locked to each other. An observer on each one of them would see the other always pinned on the same place in the sky. However in the application this appears to be so only for Charon. If I set the observer's location on Pluto I see Charon rise from the west and set to the east twice for every rotation of Pluto. I see that Pluto's rotation and Charon's revolution periods are correctly equal to one another (about 6,4 Earth days long), but Charon appears to orbit Pluto in the opposite direction than it should, hence its apparent motion to a Pluto-based observer.

    It would be much appreciated if this could be corrected in some future version of the program.
    Thanks in advance.

    Sorry if this has already been pointed out at some other thread.

      It's already fixed - if you update data for your system.ini file from default settings.
