re: Solar system just got bigger
This story was front paged with beautiful illustration in my local newspaper, wonder of wonders. But still, we need some clarity here. WHY, exactly, is Charon included as a 'planet'?
(a footnote to the story as published in my newspaper stated that Pluto-Charon is to be considered a double planet, which is supposed to explain why Pluto's satellite is the third new planetary member.)
