Study of Recent Interstellar Asteroid Reveals Bizarre Shape (bbc.com)
JoeRobe writes: A few weeks ago an interstellar asteroid, now named "Oumuamua," was discovered passing through our solar system. Being the first interstellar asteroid to ever be observed, a flurry of observations soon followed. This week, an accelerated article in Nature reveals that Oumuamua is more bizarre than originally thought: it is elongated, with a 10:1 aspect ratio, and rapidly rotating. This conclusion is based upon comparisons of its time-dependent light curve to those from 20,000 known asteroids.
Let's not name it or decide how weird it is yet, thanks.
Depends in it's made of useful materials for the trip, like ice (H2O)
