Voyager 2, which flew by the giant planet in 1989.
No human has ever traveled through the asteroid belt, as it is filled with millions of small rocky bodies that could pose a danger to spacecraft. Spacecraft that have traveled through the asteroid belt, such as NASA's Dawn mission, are designed to navigate safely around the asteroids.
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.
as far as i am aware it is haley's comet
As of 2011, only one spacecraft has passed relatively close to Neptune. 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 five inner moons: Naiad, Thalassa, Despina, Galatea and Proteus.
Yes, but they have not landed.
yes
Just one.
Yes.
Nobody knows for sure. If they do know, they aren't telling.
No, nobody has travelled to Saturn. However, spacecraft have visited it.
I think that they have tried but failed. But i could be wrong...

The First Aircraft that ever visited the planet is the dumbest question, Don't you know how to specify questions fool?
A spacecraft left earth in late 1957 and returned in early 1958. Other than human spacecraft, no alien space craft has ever left or come to visit our planet, that we know of. It is possible some alien space craft may have visited earth millions of years ago. It is highly unlikely any craft has done so within the past few centuries.
