Planet Formation and the Origin of Life

Dante S. Lauretta, Professor, Planetary Sciences/Lunar and Planetary Laboratory It is generally accepted that planets or their satellites are required for life to originate and evolve. Thus, in order to understand the possible distribution of life in the Universe it is important to study planet formation and evolution. These processes are recorded in the chemistry and mineralogy of asteroids and comets, and the geology of ancient planetary surfaces in our Solar System. Evidence can also be seen in the many examples of ongoing planet formation in nearby regions of our galaxy. Finally, the variety of observable extra-solar planetary systems also provides insight into their origins and potential for life. These records will be discussed and compared to summarize our current understanding of planet formation and the accompanying processes that may lead to the origin of life throughout the Universe.
