One thought on “Pluto secedes…

    Pluto and Charon have rotations synchronized to each other and are in highly circular orbits, raising the possibility of constructing a space elevator to bridge the 17773 km distance between their surfaces. This distance is less than half the 36000 km to geosynchronous Earth orbit and the gravitational fields are much lower. A Pluto-Charon space elevator would not be in orbit but would instead be anchored to Charon.
