Rama

Yes, Rama would have been a very appropriate name, particularly because, in the book, it was the very odd lightcurve that was the first thing that drew attention to the object. A long, thin object in a strongly hyperbolic orbit. There is no indication that this isn’t a natural object but the parallels with the Clarke’s novel are quite interesting. It’s definitely worth a read if you haven’t read it already. There was also a very good Radio 4 adaptation which must be available somewhere.
