The 3-body problem never ceases to amaze me. I've had so much fun playing with choreographies over the last few years, and detecting chaos. Despite the N-body problem being age-old, there's still so much cutting edge work being done on figuring out where various patterns and (sub)structures come from. The Kepler dataset [1] has provided a brilliant starting point to probe a lot of seemingly insane planet configurations. One of the most fascinating restricted problems I've worked on is the Sitnikov problem [2].
