It's not clear what you mean by "visited", here.
All man-made spacecraft ORIGINATED from Earth. Some of them later RETURNED to Earth as well, and quite a few of them were designed to STUDY Earth (for example, weather satellites).
Yes. Every spacecraft ever made by humans originated on Earth and most never went farther than an orbit around Earth. Many have returned to the surface.
Humans, no. Unmanned spacecraft, yes.
yes
There are many planets in our solar system that have not been visited by a spacecraft. As of now, the planet Uranus has not been visited by any spacecraft.
yes
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.
Astronauts have visited the Moon, which is not a planet but a natural satellite of Earth. Other than the Moon, astronauts have not visited any other planets in our solar system. Only unmanned spacecraft have been sent to explore other planets.
No human has really visited any planet other than Earth; the Moon isn't a planet. However, spacecraft have visited other planets, such as the Spirit and Opportunity rovers, who went to Mars
April 2008 At present the only planet in our solar system that has not been visited (either by an orbiting spacecraft or flyby spacecraft) has been the recently planet downgraded body of Pluto. There is a mission currently in motion to visit this distant outpost.
No, there have not been any space missions that have visited Uranus. The Voyager 2 spacecraft is the only spacecraft to have passed by Uranus, conducting a flyby in 1986. There are currently no upcoming missions planned to visit Uranus.
No voyager 2 or two was the only spacecraft to visit Neptune.
Any aircraft are from earth. There is no scientific evidence that aircraft from anywhere else have visited us.
