Now imagine yourself standing at the north pole, facing the direction the earth is moving through space. You rise up magically, far enough away that you can see the whole planet rotating underneath you while you yourself remain stationary. Which direction is it turning? Counterclockwise. Where is the sunlight? From your perspective, it’s on the left side of the planet. That means that the front of the planet, or the part that’s charging into oncoming meteors, is the place where morning is beginning for people on earth. The back of the planet, meaning the part that’s moving away from meteors, is where evening is beginning. It may seem funny, but every morning when you look up into the sky, you are looking in the same direction as the planet is moving. In the evening you are looking the other way. And the speed of shooting stars confirms it!
