  Most stars, perhaps even all stars, form in crowded stellar environments.
Such star forming regions typically dissolve within ten million years, while
others remain bound as stellar groupings for hundreds of millions to billions
of years, and then become the open clusters or globular clusters that are
present in our Milky Way galaxy today. A large fraction of stars in the Galaxy
hosts planetary companions. To understand the origin and dynamical evolution of
such exoplanet systems, it is necessary to carefully study the effect of their
environments. Here, we combine theoretical estimates with state-of-the-art
numerical simulations of evolving planetary systems similar to our own solar
system in different star cluster environments. We combine the REBOUND planetary
system evolution code, and the NBODY6++GPU star cluster evolution code,
integrated in the AMUSE multi-physics environment. With our study we can
constrain the effect of external perturbations of different environments on the
planets and debris structures of a wide variety of planetary systems, which may
play a key role for the habitability of exoplanets in the Universe.
