The answer: Earth would be different, often in ways that would surprise us. The title chapter, for example, gives us a second moon orbiting closer to Earth than the one we have now. The night sky is a lot brighter, but not forever. Eventually the moons collide, with one more-massive moon emerging after a period during which Earth has a Saturn-like ring. The scenarios also shed new light on the burgeoning search for life on planets orbiting other stars. \u003cbr\u003eAppealing to adult and young adult alike, this book is a fascinating journey through physics and astronomy, and follows on the author's previous bestseller, \u003ci\u003eWhat if the Moon Didn't Exist?, \u003c\/i\u003ewith completely new scenarios backed by the latest astronomical research.\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eBinding Type:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e St. Martin's Griffin\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 08\/02\/2011\u003cbr\u003e\u003cb\u003eISBN:\u003c\/b\u003e 9780312673352\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 288\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.80lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 8.40h x 5.50w x 0.80d","brand":"Neil F.
