Not to worry, the Moon’s been spiraling away from us for nearly 4.5 billion years, shortly after the Solar System was born. Back then,the Moon was in-your-face: It orbited Earth every 8 hours, was 20x closer, 400x larger on the sky, and forced tides 8,000x stronger than today. https://t.co/JgiYizWhRx — PolitiTweet.org
