At a quick glance, the Solar System appears pristine, calm, and orderly. The celestial bodies of the Solar System execute their motions with grace and precision, and have done so billions of times for billions of years, and will do so for billions of years to come. However, hidden just below the surface is evidence of the Solar System’s history of tremendous chaos and violence. From (quite literally) Earth-shattering impacts to collisions powerful enough to reverse an entire planet’s rotation, we will peer into the distant past to see the many violent events that led to the Solar System that we know today.
