Last month, astronomical software writer Bill Gray announced that he and a group of amateur astronomers had plotted the trajectory of an object that they believed to be the second stage of a Falcon 9 rocket used to launch NASA's Deep Space Climate Observatory (DSCOVR) probe in 2015. Based on observations, Gray was able to confirm that the rocket was in orbit around the Earth and had made a series of close encounters with the Earth and the Moon, which would cause it to crash into the Moon in the vicinity of Mare Orientalis. This seemed cut and dried, and resulted in some comments on social media about whether the impact would push the Moon out of its orbit as well as chastising SpaceX for not disposing of the rocket properly and even demanding that the company clean up the mess it would cause on the Moon.
