The BBC website has a post on a "alien star" having "buzzed" the sun. Apparently 70,000 years ago it may have come within 1 light year of the sun. Now that's real close, after all Pluto is all of 13.5 light hours from the sun. So it's exactly like this foreign star has buzzed an airfield (from WWII movies I recall buzzing as coming close enough to the control tower to aggravate the officer on duty).
