They finally found a chunk of something coming into the Solar System. Something much bigger than cosmic rays or dust particles.

It's worth noting that the authors estimate a closest approach of around 2pc to Kruger 60, which is only about 4pc away. That gives a closest approach of very roughly 25 or 30 degrees! So hardly a bullseye.
The close approach of 2pc seems on the large side for the object to have originated in Kruger 60's Oort cloud, especially given the small mass (less than half a solar mass) of the system. But the low velocity is suggestive. |
