text: In the second paragraph, The writer claims that Venus is referred to as Earth's "twin''. But the only evidence he gives to back up this claim is that "Venus is the closest planet to Earth in terms of desnity and size." but in reality, Earth and Venus are very differnet. Earth is much safer in terms of temperature, pressure, and gas compaired to Venus. Venus has a blanket of gas that covers it that is, "almost 97 percent carbon dioxide." Plus, on its surface, "temperatures average over 800 degrees Fahrenheit." with the level of carbon dioxide and the ragging heat that it has, nothing is safe for long on Venus, especially humans. He does state that several spacecrafts have attempted to land on Venus, and only lasted a few hours, but he doesnt state what happened to them. most people would guess that they just melted entirely because of the extreme heat, which is most likely what happened, but we don't know for sure.
