{"product_id":"9780312673352-secondhand-what-if-the-earth-had-two-moons","title":"What If the Earth Had Two Moons?","description":"\"What if?\" questions have always stimulated people to think in new ways. \"What if the Earth Had Two Moons\" leads us on a fascinating 10 world journey exploring what the Earth would be like if conditions in the universe were slightly different. 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.","brand":"Secondhand Stock","offers":[{"title":"Default Title","offer_id":49033265512667,"sku":"9780312673352-SECONDHAND","price":12.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0523\/7646\/9701\/files\/d41f6713-ab84-4064-89cc-84115a5dedb0.jpg?v=1785237198","url":"https:\/\/bookgrocer.com\/products\/9780312673352-secondhand-what-if-the-earth-had-two-moons","provider":"Book Grocer","version":"1.0","type":"link"}
