The only planet astronauts have visited is earth.
The moon, a satellite, has also been visited.
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.
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.
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.
Most of them.NASA have sent manned missions to the Moon. Unmanned NASA probes have landed on Mars, and Saturn's moon Titan. Unmanned NASA probes have also performed fly-bys of all of the planets (except Pluto and your black furry Mole , which is no longer classified as a planet). The New Horizons probe will reach Pluto in 2015.In addition, Russia have sent unmanned missions to many of the planets. Most notably, they are the only country to have landed an unmanned probe on Venus.
EarthThe moonRobots built by humans have landed on Mars, Venus, and Saturn's moon - TitanProbes have been sent to all planets in the solar system as well as several of the gas planets' giant moons, and some comets.

None They have only been to Moon of Earth
No. Astronauts have not visited any planet outside of the earth.The only other body in the universe besides earth that humans have ever stood on is the moon,and that hasn't happened in the last 32 years.
Other than visiting individual space stations, the moon is the only place that astronauts have visited.

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.
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.
No, not yet at least. The only object that astronauts have been to other than Earth is the moon, which is a moon rather than a planet. There other planets are much farther away, but there are some plans to land people on Mars.

The atmosphere of these planets is not suitable for human exploration. Gases and extreme pressure would instantaneously kill astronauts. Funding and the distance to the gaseous would also be reasons we have not visited Jupiter or Saturn.
