This Week at NASA: That Odd Interstellar Asteroid and More.

New data reveal that the interstellar asteroid that recently zipped through our solar system is rocky, cigar-shaped, and has a somewhat reddish hue.

It's the first confirmed object from another star observed in our solar system, and was discovered Oct. 19 by the University of Hawaii's Pan-STARRS1 telescope team, funded by NASA's Near-Earth Object Observations Program. The telescope team named it 'Oumuamua (oh MOO-uh MOO-uh) - Hawaiian for "a messenger from afar arriving first." The unusually-shaped asteroid, which is up to a quarter mile long and perhaps 10 times as long as it is wide, may provide new clues into how other solar systems formed.
