Once that telescope is in place, can they tell exactly where the asteroid would hit Earth, or is it more like everybody on this hemisphere take cover?

- defrost 3y agoComputer says yes: https://gravitysimulator.org/ https://gravitysimulator.org/ https://spaceengine.org/ https://spaceengine.org/ Once the mass, velocity, heading of an object is known it becomes easier to track and fine tune parameters meaning time of intersect with earth can be calculated which gives orientation of planet and entry attitude. An exact street addres | sub metre grid reference is a big ask, but the "line of breakup" arcing across a narrow slice of the planet is realistic.
