Physics, Astronomy & Cosmology / Do comets get smaller as they travel through space?

Marc asked the Naked Scientists:
I have been wondering about comets and the great distances they travel:Â
Do comets get smaller and smaller as they travel through space - after all they are travelling millions of miles and are "giving off" material which make up their tails?
How come they are able to last as long as they do?
Great show - many thanks.
