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.
How was the planet Uranus been observed
no there are not any storms on uranus
No, Uranus is completely gaseous and has no land that would slide. Walking on Uranus would be like walking on a cloud, only much stinkier because there is a lot of methane.
No, Uranus does not orbit around any plants. Uranus doesorbit around the sun.
