The Sky at Night Book of the Moon - A Guide to Our Closest Neighbour | Dr. Maggie Aderin- Pocock

But far from being just a big rock out in space, the Moon has a phenomenal power over the earth, with its ability to create great waves, dictate the length of the day and summon the seasons. She uncovers the way the Moon has captured our imaginations, contemplates how it was formed, and uncovers why we need the Moon to protect our fragile earth.
