A Long Distance Look from LORRI images were published recently.
Pluto and Charon look like shrunken ovals here:
Why is this?
Is it due to Pluto and Charon's phases? Is the distance enough to observe not full phase?
I calculated that since the speed of Pluto is 4.6 km/s and the speed of New Horizons is 14.6 km/s, then the angle it observed is 17 degrees.
Is this correct and is this enough to observe not full phase?
