According to wiki, our mean orbital speed (it’s not the same for the entire orbit, we’re orbiting the sun in an ellipse with the sun at one foci and we’re faster closer to the sun and slower at the other end of the ellipse) is 107,218 km/h which is… 66623 mph.
If you’re talking about how fast the universe is expanding, as in how fast everything is moving outwards and away from each other, check out this site. They say we’re accelerating at between 50 and 100 km/s/Mpc.
edit :: I just actually thought about that last number. Far out that’s fast!
