Well, you know what they say about Wikipedia...
Anyway, 600 million years is a long while, I wouldn't say it's an absolute necessity to look for another home in the 22nd century unless we really continue fucking things up on Earth that much, although I'd like to see us exploring the stars, I'd say it'll be another few hundred years at least before we find a new planet to live on. And that's being very optimistic IMO.
