AbstractOne of the interesting arguments for a space impact mission to asteroid 3200 Phaethon is to create an artificial Geminid meteor shower. In this work we investigate the artificial shower’s dates of observability and dependence on ejecta velocity using dust trail theory. We find that when the dust ejecta velocities are 200m/s the artificial meteor showers start to be visible in 2204 and continue for about 30 years. If the dust ejecta velocity is 20m/s they only last 10 years from 2215 to 2225. Thus, the onset of artificial shower activity begins sooner and lasts longer with higher ejecta velocities. To produce an artificial meteor shower with 3200 Phaethon as the parent will require higher impact energy than the Deep Impact spacecraft delivered to 9P/Tempel 1.
