The first known asteroid to visit our Solar System from interstellar space has been given a name. The interstellar interloper will now be referred to as 'Oumuamua, which means "a messenger from afar arriving first" in Hawaiian.
Now, new data reveal 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. That aspect ratio is greater than that of any asteroid or comet observed in our solar system to date. While its elongated shape is quite surprising, and unlike asteroids seen in our solar system, it may provide new clues into how other solar systems formed.
I got challenged to do NaNoWriMo this year. Go on, guess what's just turned up in my story?Disembodied wrote: ↑Mon Nov 20, 2017 6:02 pmNow, new data reveal the interstellar interloper to be a rocky, cigar-shaped object with a somewhat reddish hue.

Generation ship, anyone?
). The least Invasion of the Saucer People report I've found so far is in the Grauniad: While many astronomers believe the object is an interstellar asteroid, its elongated shape is unlike anything seen in the asteroid belt in our own solar system. Early observations of ‘Oumuamua show that it is about 400m long but only one tenth as wide. “It’s curious that the first object we see from outside the solar system looks like that,” said [professor of astronomy at Harvard University Avi] Loeb.

True – although much could depend on the size of the builders …pleiadian wrote:At "just" 400m, this hardly fits the definition of a generation ship.
