A Γ-based Forecast of Interstellar Object Arrivals into the Inner Solar System Using Gaia data
To the point
Lukas Zalesky and team estimate that about 7 interstellar objects pass within 1 AU of the Sun each year, most moving under 100 km/s with a median around 38 km/s, originating mainly from the Milky Way's thin disk, and this suggests that future rendezvous with these objects could be scientifically feasible.
