There's an article in the Guardian with Brian Aldiss claiming "I was there first" about the discovery of Kepler 22b. I've read the books, however the article doesn't make clear on what grounds Aldiss was there first.
Is it merely that he imagined an earth-like planet hundreds of light years aweay (in which case many other people have too); or is there a direct parallel?
I believe Kepler is a two star system, like the Heliconia books. The key feature in those books however was that the planet Heliconia has a 'normal' year around the first star Freyr, however both are in a 5000 year orbit around the other star Batalix, which gives rise to 1000 year seasons as Heliconia enters Summer and then back out to Winter from an eccentric oribt of Batalix. Does the Kepler system have this nature too?
