No spacecraft has visited all the planets.
All of the eight planets have been visited or orbited by space probes.
All of the planets in the Solar System have been visited by machines except for the planet Pluto. There was a machine that was launched in 2004 for a flyby to Pluto in 2014.
Depends on whether you say Pluto is a planet or not. If you say it isn't, then there are no planets that haven't been visited by a spacecraft. If you say it is, then there is one that hasn't been visited yet, but one is on the way.
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.
In episode II, two planets visited are Kamino and Tattooine.
None have. The only astronomical body outside of Earth that people have visited is the moon. The nearest planet is something like 200 times FARTHER than that.
Yes, I can. -- Complete list of planets that humans have visited: Earth -- Complete list of other bodies outside of earth that humans have visited: The Moon.
Some people believe that spaceships from other planets have visited Earth, but no one has ever been able to prove it.
Earth.
The only planet astronauts have visited is earth. The moon, a satellite, has also been visited.
There is no generally-accepted evidence that this occurred. The "alien visitors" theories concerning UFOs and alleged abductions are scientifically unsubstantiated. It is possible that non-intelligent lifeforms may have reached Earth in the form of organic material thrown into space by collisions of other planets or stars.
