Clarke’s classic novel Rendezvous with Rama, in which a gargantuan but silent alien spacecraft enters the solar system with a trajectory that will slingshot it around the sun and send it back out again, leaving a human research mission with a limited amount of time to investigate it. This is a great and simple set-up for a Big Dumb Object first contact mystery, clearly drawn from Arthur C. They will have only five days to arrive at Janus and, if it doesn’t prove hostile, land on it and investigate it. Clearly no moon at all but rather an inexplicable alien artifact, the human race sends their only nearby ship scrambling after it: the comet miner Rockhopper, with a crew of about 150 under captain Bella Lind.


In the year 2057 one of Saturn’s smaller moons, Janus, unexpectedly departs from its orbit and begins to accelerate out the solar system. Pushing Ice by Alastair Reynolds (2005) 460 p.
