At present humanity has the ability to land astronauts on only one planet, the Earth. We are also able to land astronauts on one natural satellite, the moon, if we put out the effort. Equipment to accomplish travel to the moon in not available immediately and would have to be rebuilt
The inner planets are the only planetary bodies in the Solar system that have what could be called a surface. It is possible that Neptune and Uranus also have solid surfaces, but it is not conclusively known. Saturn and Jupiter are gas giants, and while the atmosphere of the deepest levels might be dense enough to support mass, the pressure would be so great that anything that reached those depths would be crushed.
Each of the inner planets with the exception of Earth and Mars present technological problems beyond distance that make landing on them difficult. The Soviet Union at its height did land probes on Venus, but none lasted long enough to send back much telemetry, and the dark side of Mercury would be relatively easy to reach, but breaking out of orbit and returning to Earth would be prohibitive in the amount of fuel necessary.
While poor little Pluto is no longer a planet, its surface is likely solid as well, most likely frozen methane and/or ammonia.
We have not sent any people to land on other planets.
However, we have landed spacecraft (from the old USSR) on Venus and (from the USA) on Mars .
Mars and Venus have been landed on.
Um...astronauts DID land on the moon...
The correct capitalization would be "Did your astronauts land on the moon?"
The only planet astronauts have visited is earth. The moon, a satellite, has also been visited.
The astronauts landed on the moon, with the help of the lunar module.
The Apollo 11 astronauts landed in the Sea of Tranquility.
2,000,000,000 B.C.!
Astronaut did not land in Venus because the planet is hot. If the astronaut land on Venus, they will burn their selfs.
"Land of the Giants" (1968-1970).

In 3955 the astronauts returned to Earth to find hte apes in control in Planet of the Apes.
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 moon.
