From what I have learned, there has not yet been a robot that explored Mercury from closeup. They see Mercury since it is able to be seen by the naked eye in certain times of the night and day. It can also be seen with a telescope.
So in all:
There has not yet been a robot to explore Mercury from what I know.
I apologize if this is incorrect.

To date, no satellites or robots have directly explored Neptune. However, the Voyager 2 spacecraft flew by Neptune in 1989, providing the first and only close-up images and data of the planet.
The Sun doesn't make things blow up, but it does make Mercury quite hot.
Voyager 2 is the only spacecraft to have gone near Neptune.
Mercury is an element. Mercury is purely made up of mercury atoms.
