Only our two nearest neighbours Venus and Mars have been landed on. Landing on another planet is technically challenging and many attempted landings have failed. Mars is the most explored of the planets. Mercury could be landed on but the speeds involved and the proximity to the Sun are challenging.
What planets have humans landed on?
Several Soviet and U.S. robotic spacecraft have landed on Venus and the Moon, and the United States has landed spacecraft on the surface of Mars.What is the only planet humans have walked on?

Can you walk on Pluto?
If a person wanted to actually walk on the surface of Pluto, the astronaut would probably need to add a significant amount of weight to his gear in order to keep his feet firmly enough on the surface of the planet to actually walk around.Can you stand on Venus?
You would not survive a visit to the surface of the planet - you couldn't breathe the air, you would be crushed by the enormous weight of the atmosphere, and you would burn up in surface temperatures high enough to melt lead.Can we land on Venus?
The mission wouldn't put humans on the surface of Venus—that would be impossible to do without killing them. Instead, the humans would fly by the planet to get a closer look at the planet from above and operate a team of drones that would descend deep into the torrid atmosphere of the planet and down to the surface.Can we land on Pluto?
To travel the billions of miles between Earth and Pluto, the amount of fuel you would have to bring with you isn't a major problem for New Horizons, but for a manned mission, it would be prohibitive. Chemical fuels are heavy and you eventually hit a limit on how much mass a rocket can lift off the planet.Can you walk on Uranus?
The Surface Of Uranus Isn't SolidThe primary reason that humans cannot walk or stand on the surface of Uranus is that the surface isn't solid. Most of Uranus underneath its gaseous atmosphere appears to be composed of a slushy mixture of water, methane, and ammonia.
