Discoveries using the telescopes on Mauna Kea

Rob, yes, its orbit and extremely high velocity strongly suggest an interstellar origin. It could be a solar system object that had its orbit affected by Jupiter, but the high velocity, very similar to other stars in the solar neighborhood, strongly suggest it came from interstellar space. What's more interesting is that it seems to have passed through the solar system of another star before it got here, so it's well-traveled!
