A study published Wednesday in the journal Nature indicates that the interstellar visitor, dubbed Oumuamua, is neither an asteroid nor an alien spacecraft (as some wags had suggested) but a small interstellar comet.
“It’s the only such object discovered so far,” Marco Micheli, an astronomer with the European Space Agency and the lead author of the new study, told NBC News MACH in an email. …
[A]n analysis of new observations made by ground-based telescopes and the Hubble Space Telescope yielded a surprise: Oumuamua’s trajectory couldn’t be explained solely by the gravitational forces exerted on it by the sun and the planets — as would be the case if it were an asteroid, or space rock.
