It will be known that it will cross the Earth's orbit in some decades, but that we will have a collision, only months or years before the crash. We will have some tens of years for doing something. It won't be enough to save the Humanity, but it will be enough to build some Martian colony. The resulting collective psychosis will probably avoid this, so the Humanity will die. | |

| Oct 17, 2018 at 6:02 | comment | added | ProfRob | What is a "sharp angle"? | |
| Oct 17, 2018 at 5:59 | comment | added | PM 2Ring | "the only real constraint is that even if it does not collide with the Earth, its passage will end life" Does that mean it's moving fairly slowly? | |
