text: Venus may have a variation of attributes compared to Earth and Mars, but that shouldn't stop people from exploring the planet. Since Earth and Venus are considered "twins," they are similar according to their, "...density and size, and occasionally their distance too." (2) The author also mentions how Venus could have once been the, "...most Earth-like planet in our solar system." With that being said, if Venus was similar to Earth in its lifetime, then it could answer pondering questions like "Is there any other signs of life on other planets?" Just like Earth, Venus has, "valleys, mountains, and craters." (4) Venus' similar characteristics to Earth makes it an interesting mission for scientists.
