Every morning, the Sun peeks over the horizon, painting the sky in shades of orange and gold. Every evening, it slips away, leaving behind a blanket of stars. But the Sun isn’t really “rising” or “setting.” Instead, we’re the ones moving—riding a giant, spinning ball called Earth.
Next time you watch a sunset, remember: you’re not watching the Sun go down. You’re watching yourself turn away from it. And somewhere on the other side of the world, people are just waking up to a brand-new day.
Here’s the simple secret:
So, as Earth spins, you, your home, and your whole city move from day into night and back again. Every spot on Earth (except the very poles) gets about 12 hours of day and 12 hours of night over a full spin—though this changes with the seasons because Earth is also tilted.
