text: The author said that Venus is Earth's "twin" and that is true! Venus is the, "closest planet to Eartth in terms of density and size, and occasionally the closest in distance too.". Venus probably had what Earth has right now which are oceans. Even now, Venus is similar to Earth in terms of surface. The planet has a rocky surface and sediment and also similar valleys, mountains, etc but it's not all good stuff about Venus, the planet also has enviroments that are not suitable for human life and I don't think it will anytime soon in my life time. The author does talk about it and gives facts on why it's hard to explore Venus. It has "A thick atmosphere of almost 97 percent carbon dioxide". The clouds are highly corrosive sulfuric acid, the surface of Venus is a flaming 800+ degrees Fahrenheit. That's hot! The pressure alone is 90 times greater than Earth. A submarine accustomed to dive into our deep ocean would be crushed on the Venus surface. We won't be able to see through the thick clouds even if we hovered the planet. Therefore, it would be nearly impossible to et samples of anything!
