text: Lastly, they say that venus is our twin planet. I don't see how it can be our twin planet because it so hot and it's very radiant. The planet Venus has a rocky sediment and icludes familiar features such as valleys, mountains, and craters. Earth and Venus can be twins because Earth is not rocky it's a liquid based planet. Venus has a thin atmosphere because the heat keeps it's so hot and thin it can't get a break to even expand. But Earthis not as close, so Earth's atmosphere is a little bit thicker the Venus's atmosphere. Venus might also have some harmful chemicals. I say this because how do we know what's on the planet its could be all types of harmful gases from the sun. We never know what's there on Venus or what could happen if we go.
