Kind of amazing they haven’t been able to narrow its orbit down more precisely than that in two years’ of observation.
Last I checked, they have not reacquired the asteroid. Watch the video https://www.youtube.com/watch?v=nNh85GXFX0E
They haven't had 2 years of observation. They had a brief glimpse of it 2 years ago as it approached the sun. It's been behind the sun since then and will approach us coming from the sun, just as the meteor that exploded over Russia did.
