Yes Drakkith, I think all that would be useful if one knew the exact time and date of the photo, could calculate the orbits and trajectories of Pluto and Charon and knew the spatial positioning between the two and New Horizons. Since Charon and Pluto orbit each other in binary fashion and New...

Thank you. I should have checked this website first. It seemed intuitive to me that there must be some way to approximate the distance from which the photo was taken using known distances between Pluto and Charon and their diameters. It was a good mental exercise to understand why that's not...

Thank you! Do you have any idea of how one might calculate this based on the photo?

OK, here is the latest photo from New Horizons as published by Popular Science. Their article claims this photo was taken from a distance of 3.7 miles. Intuitively this seems way off. The known distance between Charon and Pluto is 12,200 miles. Pluto's diameter is 1,471 miles. I've been trying...
