This timely meeting (appropriately held in Toruń, the “city of Copernicus”) provided an excellent venue for researchers to review the theoretical and observational progress in the intervening years, share recent results, and make preparations for progress in the quests to learn whether our Solar System is typical and to understand how our own Solar System relates to the rest of the Universe. It had been nearly six years since the last major scientific meeting focusing soley on multiple planet systems and planets in multiple star systems in Saas Fee, Switzerland during September of 2002 (Udry et al. 2006). Here I review some of the observational and theoretical progress in understanding multi-body systems reported in Toruń.
