In 1992 we discovered the first planet outside of our solar system. Here we are now, twenty-three years later and we have discovered nearly 2,000. It is now known that most stars have at least one planet. In celebration of this achievement, here is a look at some of the highlights of the history of astronomy.
If earth was 50% larger in diameter gravity would be so high that chemical rockets would'nt be able to break the earths pull and our intire space adventure vould be nothing but a Jules Verne story.
So if the folks at Kepler 425b are like us we're just a story and a dream for them, nothing they can come and see.
My point is, it's too far way for any of our instruments to measure the 'actual' habitable zone of that system. Too much guesswork going on.
