Pluto and Charon

nh_zoom_bary_03-finalNew Horizons is closing in on Pluto. These pictures were taken during the last week of January at a range of roughly 2,000,000 km. They show Pluto and Charon orbiting around their barycenter, a mutual point above Pluto’s surface where Pluto and Charon’s gravity cancels out—this is why Pluto appears to wobble in space.

  1. What I noticed was not the wobble, but the moon’s non-circular orbit. Who are you going to believe: Ptolomy or your own lying eyes?
