Why can't people live on Neptune?
March 24, 2010 10:17PM
People cannot live on Neptune because it has no solid surface, only a molten core of liquid rock, water and ammonia. Also, it's four thousand mile thick atmosphere of hydrogen, helium and methane has temperature ranges from negative 360 degrees Fahrenheit to 900 degees Fahrenheit, winds of up to 1,200 miles per hour and chunks of molten debris whirling about. It's gravity is 114% that of Earth, and that is about the best that can be said for it, as that would add little to your weight in the second or two you would live unprotected.
