Just a few decades ago, our solar system was the only planetary system we knew. Scientists proposed theories as to how it formed, but had no other systems on which to test these theories. That all changed in 1989 with the first detection of an exoplanet, a planet outside our solar system orbiting another star. To date, we know of 2,792 other planetary systems, and studying them has revolutionized our understanding of our own system. By greatly increasing our knowledge of how our planets formed and where the ingredients for life on Earth came from, CAESAR would help us in our search for other habitable planets and possibly extraterrestrial life.
