The stars in the Milky Way are constantly drifting around, coming closer and farther in billions of years of the Solar System's history. Now and then, stars come within a single light-years of the Sun, affecting the orbits of the planets. In a new paper, an astronomer has used data from ESA's Gaia mission to calculate stars that have come within one light-year, potentially drifting through the Oort Cloud and sending comets into the inner Solar System.
