text: Venus' relation to Earth is significant because it is the closest example of another planet like Earth. The author claims that Venus is even called Earth's twin and that not only is it like Earth in its density and size, but also in the distance between the two planets. Even though the planet is very similar to Earth there are challenges to get accurate data on the planet because of the many spacecrafts that were unable to withstand the harshness of the planet. As technology advanced, the author claims that more and more missions to Venus occured, and even around the time of World War II there was a spacecraft that survived in Venus conditions for about three weeks. Venus' conditions are very harmful to the life on Earth but there may have been a possibility that life could sustain on the planet. The author describes Venus as a planet mostly covered in large oceans that could have suppported life growing there. All of these examples that the author has given supports his idea of the need to explore Venus tremedously and gives very convincing evidence and data that supports his idea.
