Pluto and Charon
Hubble Space Telescope (HST) image of Pluto and its satellite Charon. Pluto is 2390 km in diameter and Charon is 1190 km. The two bodies are so close in size they are often thought of as a double planet. At the time this image was taken the two bodies were at maximum elongation of 0.9 arc seconds. The bodies orbit 19,600 km apart. Pluto is the larger body to the lower left, Charon is at upper right. (HST, STScI-PR94-17)
