If large space telescopes were placed in the L4 and L5 lagrangian points of Neptune's orbit, could optical interferometry be used to make an aperture the size of the entire solar system? What level of resolution could be obtained of earthlike exoplanets in the habitable zone of distant stars? From how far away?
What if these telescopes were placed on solar escape trajectory in opposite directions from the sun? Could this system be used to get higher and higher resolution images of exoplanets each year as the telescopes get further away from eachother?
