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\u003cp\u003e\u003c\/p\u003e","brand":"St. Martin's Press","offers":[{"title":"Default Title","offer_id":47007786139888,"sku":"9780312673352","price":21.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9780312673352_p0.jpg?v=1763677529","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9780312673352","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
