In 2012 Buie, Tholen and Grundy wrote a paper The Orbit of Charon Is Circular.

Their models of tidal evolution predicted the Pluto/Charon would have a nearly circular orbit, an eccentricity very close to zero. There has also been speculation that obliquity is close to zero. Their models were somewhat supported by Hubble observations. But as we all know, Hubble images of Pluto and Charon are pretty low res. I am wondering if data from New Horizons has verified their predictions.

If so, this would make for a neat science fiction setting. With 0 eccentricity and 0 obliquity, the Pluto-Charon Lagrange 1 would hang motionless in the sky of Puto as well as Charon. Just as a Clarke tower would extend up and down from geostationary orbit, a Pluto-Charon elevator could extend Pluto-ward and Charon-ward from the Pluto-Charon L1. With 0 eccentricity and 0 obliquity, a beanstalk linking Pluto and Charon would not be flexed, stretched or bent by orbital motion.

The two dwarf planets could be linked. It would be a setting somewhat like Robert Forward's Rocheworld.

Per New Horizons Twitter account:

This week, the spacecraft is scheduled to carry out the first of four course correction burns to bring it onto intercept trajectory with KBO 2014 MU69... Which, IMO, ought to be given some kind of name before the probe arrives.

How we flew a spacecraft 3 billion miles to Pluto | Katie Bechtold | TEDxMidAtlantic

Published on Mar 7, 2016
Katie Bechtold was a flight controller on NASA's New Horizons mission, which sent a spacecraft to Pluto. Katie shares the story behind the 9-year epic journey, which gave us the first detailed images of the planet, along with performing scientific experiments that will help us better understand Pluto's makeup.
