text: Astronomers are fascinated about Venus, for what is there and what was there long ago. ""Astronomers are fascinated by Venus because it may well once have been the most Earth-like planet in our solar system". Venus, long ago could be covered largely with oceans and had supported forms of life. " The planet has a surface of rocky sediment and includes familiar features such as valleys, montains, and craters". So, that can be scary but still for some people is excited to know a a different planet.
