2015 BZ509 is a small asteroid which is orbiting around the sun in the wrong direction in an orbit that brings it into head on close encounters with Jupiter which should doom the asteroid in short order. However due to near perfect timing the effects of Jupiter's gravity cancels out over its orbit.

Based on orbital dynamics 2 astronomers have argued that this object must have come from outside the solar system.
