text: The author said Venus is Earth's twin because it's the closest planet to have the same density and size as Earth. The author states that we could use blimp-like vehicles to not get burnt or crushed because if the vehicle gets 30 or so miles above the roiling Venusian landscape everything would change. The temperature would drop from about 800 degress to 170 degress Fahrenheit. The atmospheric pressure would drop from 90 times greater than earths surface to about Earth's sea level if the vehicle were to be 30 miles or so above the surface.
