This is just an indicator that the comet is in orbit around the sun and comes back every so often. (as opposed to non-periodic comets which are either just passing by the sun once only..ever, or that the comets orbit is so large that to all intents and purposes it might as well be non-periodic) ......................................................... glenn durden alfa@csource.oz.au Unique Computing Pty Ltd, Melbourne, Australia The opinions expressed above are that of the author only.
