Unlike the Solar System where most of the gravitational pull comes from the Sun and is simple to model, it is much harder to describe the gravitational field near the centre of the Galaxy, where millions of stars, vast clouds of dust, and even dark matter swirl about.

If a few key characteristics such as an exoplanet's topography and rotation rate are just right, then the inner edge of the habitable zone — the region in a solar system where conditions conducive to life can arise — will be closer to the host star than is usually thought.
