Use the Starry Night Enthusiast™ program to observe Pluto and Charon. First go to Atlas mode (Favourites/Guides/Atlas), Stop Time, and find Charon (Find tab/Charon). Zoom in so that Charon and Pluto are separated by a few cm or in. Set the timestep to 3 hours. Use the single-step time button to step through enough time to determine the period of Charon’s orbit. How does your answer compare with Pluto’s sidereal rotation period given in Appendix E-2? Explain.
