How did our Solar System form over the last 5 billion years? How does our Solar System differ from the thousands of other planetary systems we have discovered around other stars? Join us for a 30-minute lecture about planetary systems, followed by a panel Q&A consisting of several astrophysicists to answer your questions about astronomy and space science.

Is our universe a black hole?" 1:58:30 Concluding Remarks Title: How to Build a Solar System Lecturer: Adolfo Carvalho Abstract: Since the discovery of 51 Pegasi b in 1995, we have found over 5,000 planets beyond our Solar System, orbiting other stars in our Milky Way galaxy. Most of these planetary systems are quite different from our own Solar System in their masses, sizes, and orbits. As we catalog these many different planetary systems, we can identify how planets form and change over time, which may help us understand the processes at play in our own Solar System. I will discuss how we currently believe our Solar System formed, from a humble cloud of dust in the Milky Way nearly 5 billion years ago into the Sun and planets we know and love today. https://www.adolfocarvalho.com/ Image Credit: Future Publishing Limited
