  • 1I/'Oumuamua is the first known interstellar small body, probably being only about 100 m in size. Against expectations based on comets, 'Oumuamua does not show any activity and has a very elongated figure, and it also exhibits undamped rotational tumbling. In contrast, 'Oumuamua's trajectory indicates that it was moving with the local stars, as expected from a low-velocity ejection from a relatively nearby system. Here, I assume that 'Oumuamua is typical of 100 m interstellar objects and… CONTINUE READING
