This animation shows the approximate size of Pluto and Charon by overlaying them on an Advanced Very High Resolution Radiometer (AVHRR) image of the United States of America. Pluto is about 2320 kilometers (1440 miles) in diameter and Charon 1270 kilometers (790 miles) in diameter. The image of Pluto is based upon Hubble observations taken of Pluto in June and July of 1994. The Charon image is based upon photometric measurements acquired by Marc Buie of Lowell Observatory.
