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.
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.
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.
Planets that have been visited by spacecrafts include Mars, Venus, Mercury, Jupiter, Saturn, Uranus, and Neptune. Additionally, the spacecraft Voyager 2 has conducted flybys of both Uranus and Neptune.
Pluto has yet to be visited by a spacecraft because it is so far away.
The US space program, including NASA, has successfully visited several planets in our solar system. These include Venus, Mars, Jupiter, Saturn, and Pluto (visited by the New Horizons spacecraft). Additionally, various probes have been sent to study other celestial bodies like comets, asteroids, and moons.
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.
No spacecraft has visited all the planets.
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.

venus was the first planet visited by the American spacecraft
All 8 of the planets in our solar system have been visited by spacecraft, either fly-bys, or actual landings. The dwarf planet pluto has yet to be visited, but a space probe called New Horizons is on its way and should reach Pluto in 2015.
hi
yes
Pluto has yet to be visited by a spacecraft because it is so far away.
Currently no clear pictures if any dwarf planet exist, as none have been visited by a spacecraft. In 2015, however, the New Horizons spacecraft will fly by Pluto, and the Dawn spacecraft will enter orbit around Ceres.
