It isn't clear to me that they have to be terribly real. Comets, for example, are handy when talking about elipses. For instance, how far away will the current comet be before it starts back again? Finding the perihelion(I'm guessing on the spelling and I'm sure the spell checker will have no idea, but it is the closest point to the sun in the comet's orbit) and the orbit's eccentricity is a quick look on AltaVista (.914 au and e=.995).
How far away will it be before it turns to start back? 11th graders in pre-calc took a few minutes thinking about it before they got these numbers to give them the axis lengths, but they all got it and were interested in the whole thing while they were working on it.
But there isn't much real world about this. Actually, I've yet to see this particular comet (Chicago weather ...) and many of the 11th graders never did see last years.
