Our solar system formed 4.5 billion years ago in an extremely chaotic environment and has evolved significantly over that time. What we see today is an organized inner solar system with four very di erent terrestrial planets. Join Dr. Shahar for an exploration of these planets as we try to understand their diversity. By analyzing rocks we can hold in our hands today and conducting experiments in the laboratory, we can probe which processes and condi- tions the terrestrial planets experienced billions of years ago.
