Can Humans Live on Uranus?
Based on scientific knowledge as of 2014, it is not possible for humans to live on Uranus. As a gas giant, Uranus lacks a solid surface for landing spacecraft or building long-term habitation facilities.
In addition to the planet's lack of a solid surface, Uranus' cold average temperature of minus 357 degrees Fahrenheit is far below the temperatures to which humans on Earth are adapted. Severe weather on Uranus can cause wind speeds to exceed 500 mph, which is also inhospitable to human life. Its atmosphere is composed primarily of hydrogen and helium, and it lacks the carbon and oxygen scientists view as essential to human life.
