That was my reaction; I'm not sure whether they meant to say the "21/Borisov, the interstellar comet for whom our system is the first solar system it has visited", or (as other comments suggest) "the first confirmed interstellar comment to visit our system". Obviously if something is only now noticed with modern technology, it's unlikely that interstellar comets haven't swung by our solar system many times before. We just don't have a record of it. |
