How fast are we moving while sitting still?

You're sitting still right now, aren't you? Totally not moving. But here's the truth: you're zooming through space faster than a fighter jet, spinning like a carousel, and orbiting like a marble circling a drain. All at the same time. You just can't feel it.
Start with the ground beneath you. Earth spins on its axis once every 24 hours—that's what makes day and night. If you're standing at the equator, the widest part of the planet, you're whipping around at about 1,000 miles per hour. That's faster than the speed of sound. You don't feel it because everything around you—the air, the trees, your house—is spinning at exactly the same speed.
