Pluto and its moon

Pluto and its moon Nix are separated by 48700 km. Neglecting atmospheric effects, should the 5.08 m diameter Mount Palomar telescope be able to resolve these bodies when they are 6.40 Af— 109 km from Earth? Assume the average wavelength of 555 nm. To determine the answer, calculate the ratio of the telescope\'s angular resolution to the angular separation of the objects.
