The first object of unambiguously interstellar origin, 'Oumuamua, passed through the inner Solar System in 2017. The existence of interstellar objects is an inevitable consequence of planet formation, but the estimated abundance and individual properties of 'Oumuamua pose many puzzles. I will discuss some of the mysteries, and the prospects for using more such objects as a new probe of planet formation.
