It Came From Outer Space -- Astronomers Find First Interstellar Asteroid

Astronomers recently scrambled to observe an intriguing asteroid that zipped through the Solar System on a steep trajectory from interstellar space -- the first confirmed object from another star. Now, new data reveals the interstellar interloper to be a rocky, cigar shaped object with a somewhat reddish hue. The asteroid, named Oumuamua by its discoverers, is up to one quarter mile (400 meters) long and highly elongated -- perhaps 10 times as long as it is wide. While its elongated shape is quite surprising and unlike asteroids seen in our Solar System, it may provide new clues into how other star systems formed.


Comments:

Is it an asteroid or probe or ship from another star system? How many asteroids have shape like this??
