The largest asteroid is CERES, in the asteroid belt between Mars and Jupiter.It is 580 miles (930 km) in diameter , about the size of Texas.It accounts for about 32% of the total mass of the belt.
Unfortunately, no one has ever visited Neptune as we currently lack the technology to venture out that far into space. Did you know that the Voyager 2 was the first and only spacecraft to ever visit the planet?

Only one through 2009. The Voyager 2 probe visited Neptune in 1989, having previously passed Jupiter, Saturn, and Uranus. Voyager 2 took the first close-up photos of the Neptunian moon Triton and discovered 5 new inner moons.

The First Aircraft that ever visited the planet is the dumbest question, Don't you know how to specify questions fool?
Yes. A spacecraft has visited this planet. They came in peace. The space creatures discovered that humans fought wars with each other. As a result they wanted nothing to do with such wild animals so they left and went to a more civilized world.
Every known spacecraft began on earth and went to other places. That's also true of every known drawing, component, fragment, subsystem, and model of spacecraft. Few of them ever returned to earth.
