Submission + - First Extrasolar Object Observed Racing Through Our Solar System (space.com) 1
Enigma2175 writes: For the first time, scientists have observed an object they believe came from outside our solar system. The object is in a hyperbolic orbit that will send it back into interstellar space. From Space.com:
The object, known as A/2017 U1, was detected last week by researchers using the Pan-STARRS 1 telescope in Hawaii. "It's long been theorized that such objects exist — asteroids or comets moving around between the stars and occasionally passing through our solar system — but this is the first such detection," Chodas added. "So far, everything indicates this is likely an interstellar object, but more data would help to confirm it."
