Using the University of Arizona's Large Binocular Telescope atop Mt. Graham in southern Arizona, Dr. Paul Wiegert of Western University in Canada, led a team of astronomers who have determined that a 2 mile diameter object bucks the solar system traffic by traveling in a direction backwards to all of the planets. In their March 30, 2017 article in the journal Nature, these astronomers confirm that 2015 BZ509, travels about Jupiter on a path in a direction opposite to nearly every other member of our solar system. Amazingly it has avoided a collision with Jupiter by using the giant planet's gravity to maintain a path that has been stable for a million years or so. This astounding trick is performed as 2015 BZ509 passes once inside and once outside of Jupiter's orbit as they both travel about the Sun. The resulting effect of Jupiter's timely gravitational pulls on this small asteroid are exactly right to keep it from having a collision or from being ejected from the solar system.
