No, Neptune does not have human or human made objects. It is to cold on Neptune so therefore, nobody has ever been on Neptune.
No satellites have directly explored Neptune, but the Voyager 2 spacecraft did a flyby in 1989, providing valuable data and images of the planet. Currently, there are no dedicated missions to Neptune, but some spacecraft may conduct flybys of the planet as part of their trajectories to other destinations in the outer Solar System.
