I want to know the answer to the following question:
When did a spacecraft get closest to Neptune?
All the background I'm provided with is that "Because this was the last major planet the spacecraft could visit, it was decided to make a close flyby of the moon Triton, regardless of the consequences to the trajectory, similarly to what was done for Voyager 1's encounter with Saturn and its moon Titan.". Is that enough to answer the question?
Answer: no
