Hi lklaes, welcome to the UT forum.

These were two cool papers you've pointed to (traversable wormholes & extra solar comets). It hadn't occurred to me that comets would be as easy to see as terrestrial planets. I'm guessing that around very young stars, they may be so plentiful that the search for young terrestrial may be made more difficult because of them.

i have one question that whether the nucleous of the extra solar comets is small or big or different than the small comets, are they bigger than any one planet? or can not be described.

The assumption is that the nuclei will be the same size as the ones in OUR Solar System.
