Speed of the Earth around the sun: Approximately 67,000mph.

The sun moving around the galaxy: Approximately 250 km/s (559,234 mph).

The speed of the galaxy moving in the universe: Approximately 630 km/s (1,409,269 mph).

During the times when all of these things are moving you in the same direction, then, you could reasonably expect to be moving at 2,036,503 mph while standing still.

That’s .3% of the speed of light.
