Hi DA,

That's not such a bad idea. I have always visualized/assumed that when comets run out of volatiles that only ashes are left. It could be that a large cohesive object is what remains.

Another assumption that I, and I am sure others as well, make is that all cometary bodies are in long period solar orbits. I realize that a comet is almost by definition in a solar orbit, but maybe we could have rocky bodies with embedded volatiles. For example a planetary moon. These could outgas over the ages to form bodies such as Hyperion.

What would you call something of this nature? A cometary moon?
