Like Al Cohen said. Humans haven't been on any planet other than earth, however probes have been to all the planets. There's is even one headed for the now dwarf planet, Pluto, and will arrive in 2015. We have also landed on all but 4 planets (Mercury, Saturn, Uranus, and Neptune) We've landed probes on Venus, on Jupiter (technically we haven't landed since there is no land but more like floated down till the heat and pressure destroyed craft), and also Mars (which has record for most visits), we've even landed on Saturn's moon, Titan (which technically isn't a planet but it is more similar to planet, specifically Earth, than any moon since it has an atmosphere, weather, and even oceans and lakes of liquids but instead of water, it's liquid methane).

The Pioneer 10 spacecraft was the first to travel beyond all planets on June 13, 1983.
The deepest humans have traveled into the Earth is about 7.5 miles (12 kilometers) through deep mines. This achievement was in the Kola Superdeep Borehole in Russia.
The moon is the farthest a man has traveled. Mars is planned for 2018.
The greatest inaccuracy in Copernicus' model of the solar system was that he still believed that planets moved in perfect circles, when in fact they move in ellipses. This led to inaccuracies in predicting planetary positions.
The Man Who Traveled in Elephants was created in 1948.
He showed that the planets traveled in elliptical orbits

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.
As of now, no human has traveled to other planets in our solar system. All crewed space missions have been limited to the Moon and low Earth orbit. However, unmanned spacecraft have been sent to planets like Mars and Venus for exploration.
