Last year a visitor came to our inner solar system. To us it looked like a faint spot of light, moving quickly relative to the fixed stars. We’d seen similar things countless times before – lonely rocks, remnants from the formation of our solar system, drifting on their endless orbits around the sun and faintly glimmering with its reflected light. Nothing unusual about such asteroids and comets, but what made this object special was its trajectory. It was not in orbit around the Sun at all. Rather, it appeared to have fallen in from interstellar space, and was on its way back out again. The object is 1I/2017 U1, better known as ‘Oumuamua. It’s the first chunk of interstellar space debris we’ve ever spotted passing through our solar system. It caused a justifiable stir at the time. Hell, WE even did an episode on it.
