Bizarre Interstellar Asteroid 'Oumuamua'

Among the strangest things about the object is its bizarre, elongated shape, estimated to be some ten times as long as it is wide. Spinning on its axis every 7.3 hours, its extreme brightness variations are unlike any known asteroid or comet from our own solar system. Thus, it apparently is an asteroid and not a comet. Thought to be dense, possibly rocky or with high metal content , the European Southern Observatory (ESO) reports it lacks significant amounts of water or ice, and that its surface is now dark and reddened due to the effects of irradiation from cosmic rays over millions of years.
