space probes have crossed Pluto's orbit, but never have visited the planet because Pluto was not in alignment with the flight path of the space probes.
All of the eight planets have been visited or orbited by space probes.
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.
aside from earth, the planet that has been visisted by the most probes, is often said to be mars, however other scientific research has also proven that venus and Jupiter had also been visisted by several probes every 200 - 400 years. mars however is often visited by probes every 50 - 100 years.

If by humans visiting you mean , Which planet's have had humans land on that planet the answer is none. The only other place in space that humans have visited is the moon.

Humans have visited NO planet outside of Earth. Humans have visited the Moon, which is not normally considered a planet.Unmanned probes sent by humans, on the other hand, have already visited several planets.

At current we have sent, or are sending, probes to all of the planets in our solar system. The probe Voyager has visited several planets, including Jupiter and Neptune, while Cassini is currently in orbit around Saturn.
yes
Humans have not technically visited any planet. We have sent landing craft to Mars and Venus though. Those missions were in exploration of possible future human habitats, but neither planet is suited for human survival.
