|Charon (left) and Pluto|
Distance from Pluto to Charon: 18,500 km
Diameter of Pluto: 2,400 km
Diameter of Charon: 1,200 km
Center to center distance on screen: 4.25"
Diameter of Pluto on screen: 0.5"
The on screen distance is 8.5 times the diameter of Pluto. The real distance is 7.7 times the diameter of Pluto, so I would say this photo does a pretty good job of showing the relative sizes of and distances between Pluto and Charon. They must be both about the same distance from the camera.
This photo was taken several days ago. Since then the probe has gotten so close to Pluto that it can no longer get both critters in the same frame.
|Orbits of Pluto's moons. Pretty cool that they were able to put together this image that shows all five of the critters.|

I was pronouncing Charon 'Chairon', in my mind anyway, I don't think I ever actually said it, but it's supposed by pronounce Sharon, like in Charlotte.
