text: As the author said, Venus is often referred to as Earth's twin. That is because Venus is closer than all the other planets to Earth in density and size and is sometimes the closest to Earth when the rotations of the planets meet up next to each other. A long time ago Venus was pretty much another planet Earth because it most likely had oceans and could support life forms and it had some of the same features that earth has like mountains, valleys, and craters. Scientists would love to be able to study the atmosphere of Venus and would want to know what happened to the oceans. They would also want to know the similarities and differences it has to the features of Earth.
