Apart from Earth, no humans have ever been on another Planet, whether they be Canadian, Irish or Bengali.
It has never been a planet, some people might of thought it was a planet, but it has never officially been one.
Ever since July 1, 1867.
The Moon and Earth
no, because the moon isn't a planet, and earth is the only one.
Yes mariner 3 has been to the planet Saturn
Nobody has ever been to the planet Mars because the physical make-up of the oxygen, let alone the planet itself is not as it should be for human organisms such as yourself to survive.
No highly civilised planet has ever been discovered to date. Including the one you are stood on.
No human has ever been to another planet except the moon. These days the moon is not considered a planet but it was in ancient times. No human has ever been to Earth because that implies you're back from travel. We are all here already.
Mars where no human has ever been.
The only planet humans have ever been on is Earth.
No person has ever been to the planet Uranus or even to the moons of the planet Uranus (which would be much easier to visit). Indeed, human beings have never been anywhere farther than the moon. Automated probes have been sent to the edge of the solar system and out into interstellar space, but human beings have not gone nearly that far.
As for as is known no earthlings have ever been on Mars.
