We can build a telescope to see this by the way. The lens being the gravitational warping of spacetime by the sun. We go waaaay past the orbit of Pluto (I forgot the exact distance) and send probes there. We can have quite nice pictures of planets up to pretty nice distances.

Easy trip to make; it took the voyagers only about 40 years to pass Pluto?

  Depends on your definition of “easy”. Here’s the wiki article about it.

    FOCAL would be able to observe only objects that are right behind the Sun from its point of view, which means that for every observed object a new telescope would have to be made.[3]: 33 [5]
    
    Ah….

    Thinking about it this isn’t necessarily true in that moving the FOCAL relatively little could yield new things to observe (even microarcseconds). So you wouldn’t need a new FOCAL to measure each new thing. However each FOCAL would be measuring a miniscule bit of space over its lifetime. Which means for each distinct object that isn’t basically a neighbour in angular terms to a FOCAL sent you’d need a new telescope probably. Unless our long term energy generation/harvesting and propulsion in deep space significantly improves technology wise.
