I can't make a fair comparison between the object in TFA and Oumuamua, the presumed interstellar object that passed through our Solar System not long ago. For the latter, a "Project Lyra" study [1] posits a combination of Earth and Jupiter gravitational assists to catchup with Oumuamua. Could a similar approach work for this comet?
