摘要

Sir: Last year, Oumuamua, the first asteroid from interstellar space, was discovered. It stirred a lot of attention because it represented the discovery of a class of objects which had been hypothesized for a long time. Almost equally interesting were its brightness variations, which hinted to a very elongated object (Spaceflight Vol 60 No 5 p. 28).I4IS proposed a mission to catch up with the retiring asteroid, but its large receding velocity made a rendezvous quite a difficult endeavour. The aforementioned article finished by pointing to the possibility that ongoing or near-future all-sky astronomical surveys would probably find some other interstellar asteroid in the next few years. In fact, it seems that when I wrote these sentences it had already been found (1).
