Earth orbits the Sun at about 30 km/s, which is roughly 107,000 km/h or about 67,000 mph on average.

Quick Scoop: The Numbers

  • Average orbital speed: about 29.8 km/s (18.5 mi/s).
  • That’s around 107,000–108,000 km/h (about 66,000–67,000 mph).
  • At this speed, Earth could travel its own diameter in about 7 minutes and the distance to the Moon in roughly 4 hours.

You’re riding a planet that’s constantly sprinting through space, yet everything feels completely calm beneath your feet.

Why the Speed Changes a Bit

Earth’s path around the Sun is a slightly stretched circle (an ellipse), not a perfect circle.

Because of that:

  • At perihelion (early January, when Earth is closest to the Sun), it moves a little faster, around 30 km/s.
  • At aphelion (early July, farthest from the Sun), it slows slightly, closer to 29 km/s.
  • The difference is only a few percent, so the average speed stays near 30 km/s.

A nice way to picture it: like a skater in an elongated loop—speeding up at the tightest turn, gliding more gently at the widest part.

Other Motions You’re Also Doing

At the same time as Earth orbits the Sun:

  • Earth spins on its axis (giving us day and night).
  • The whole solar system orbits the center of the Milky Way at hundreds of km/s.
  • The galaxy itself is moving relative to other galaxies.

So even while you’re sitting still, you’re caught up in several huge, overlapping motions through space.

Mini Forum-Style Take

If this were a forum thread titled “how fast is earth moving around the sun,” the top-voted reply would probably say:

“About 30 km/s, or ~67,000 mph, on a slightly oval path. Fastest in January, slowest in July—but on average, around 107,000 km/h.”

And then someone else would jump in to add that even at that speed, you don’t feel anything because you, the air, and everything on Earth are moving together in the same smooth orbit.

TL;DR: Earth moves around the Sun at roughly 30 km/s (about 107,000 km/h or 67,000 mph), a bit faster when closer to the Sun and a bit slower when farther away.
