"Pluto and Charon were observed for an entire rotation of each body; a "day" on Pluto and Charon is 6.4 Earth days. The first of the images was taken when New Horizons was about 3 billion miles from Earth, but just 126 million miles (203 million kilometers) from Pluto — about 30% farther than Earth's distance from the Sun. The last frame came 6.5 days later, with New Horizons more than 5 million miles (8 million kilometers) closer." The wobble easily visible in Pluto's motion is due to the gravity of Charon, about one-eighth as massive as Pluto and about the size of Texas. Our view of Pluto and Charon is only going to get better as New Horizons zooms towards its July fly-by.
