I just finished reading a story about four people who travel in a cube shaped space car, eating canned soup and peaches and also cake. They explore the ruins of a long-dead civilization on Mercury, then head for Venus to meet a hyper-evolved race of spiritually advanced people with withered little legs and big noble brows. These Venusians subsist entirely on liquids and have lost their teeth through a combination of desuetude and a flawed interpretation of evolution. I'm not here to ridicule, but rather to note that our solar system was more interesting in 1919 than it is today.
