  • With the recently discovered interstellar object 1I/2017U1 (1I/'Oumuamua) we have to realize that the Solar System is not isolated, but part of a larger environment with which we interact. We compare the kinematics of 1I/2017U1 with simulations of the Milky Way Galaxy and Gaia TGAS data to estimates the local density of objects similar to 1I/2017U1 and to investigate its possible origin. We find that about 1.3\,Myr ago 1I/2017U1 has passed within a distance of $0.16$\,pc from the nearby star… CONTINUE READING
