What If the Earth Had Two Moons?

Suitable for adult and young adult readers alike, this book features a collection of essays that offers insights into the Earth, and sheds light on the burgeoning search for life on planets orbiting other stars.

---

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 that won't last forever. Eventually the moons collide, with one extra-massive moon emerging after a period during which Earth sports a Saturn-like ring. This and nine and other speculative essays provide us with insights into the Earth as it exists today, while shedding new light on the burgeoning search for life on planets orbiting other stars. Appealing to adult and young adult readers alike, this book follows on the author's previous bestseller, "What if the Moon didn't Exist?", with completely new scenarios backed by the latest astronomical research.
