  bibo_abstract:
  - 3I/ATLAS is the third interstellar object discovered to date, following 1I/‘Oumuamua
    and 2I/Borisov. Its unusually high excess velocity and active cometary nature
    make it a key probe of the Galactic population of icy planetesimals. Understanding
    its origin requires its past trajectory through the Galaxy to be traced and the
    possible role of stellar encounters to be assessed, both as a potential origin
    and a perturber to its orbit. We integrated the orbit of 3I/ATLAS backward in
    time for 10 Myr, together with a sample of Gaia DR3 stars with high-quality astrometry
    and radial velocities, to identify close passages within 2 pc. We identify 93
    nominal encounters, 62 of which are significant at the 2σ level. However, none
    of these encounters produced any meaningful perturbation. The strongest perturber
    Gaia DR3 6863591389529611264 at 0.30 pc and with a relative velocity of 35 km
    s−1, imparted only a velocity change of ∣Δv∣  ≃  5  ×  10−4 km s−1 to the orbit
    of 3I/ATLAS. Our results indicate that no stellar flybys within the past 10 Myr
    and 500 pc contained in Gaia DR3 can account for the present trajectory of 3I/ATLAS
    or be associated with its origin. We further show that 3I/ATLAS is kinematically
    consistent with a thin-disk population, despite its large peculiar velocity.@eng
