[space] The First Interstellar Comet Ever Detected Was Lonely … Understanding sad comet 2I/Borisov. ‘Borisov is unlikely to skim by another star. More than one astronomer told me that the chances are nearly zero. The distances between stars are simply too big. “If you had a collision between the Milky Way and another Milky Way, you could collide the galaxies and no two stars would ever hit,” David Jewitt, an astronomer at UCLA who studies comets, told me. Astronomers believe Borisov coasted alone for hundreds of millions of years, even billions, through space before reaching us. “In that amount of time, you might pass by one star,” Jewitt said. “So for Borisov, maybe this is it.”’
