Max, I'm professing ignorance, not scepticism. No doubt extrasolar planets exist (the converse is, statistically, absurd), and I think I recall that some have been detected. I just don't recall anything more about those that were detected. (dumb ignorant -e)

But to make this a word-post: if "solar" is limited to our star, and not to stars generally, what do you call a planetary system around another star? Is there any term less cumbersome than "extrasolar system"?
