Synopsis: What if? questions stimulate people to think in new ways, to refresh old ideas, and to make new discoveries.What If the Earth Had Two Moonsleads us on a fascinating ten-world journey exploring what the Earth would be like under alternative astronomical conditions. In each case, the Earth would be different, often in surprising ways. 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. These different scenarios also provide us with insights into the Earth as it exists today and they shed new light on the burgeoning search for life on planets orbiting other stars. Appealing to adult and young adult alike, this book follows on the authors previous bestseller,What if the Moon Didnt Existwith completely new scenarios backed by the latest astronomical research.
