The sun (and its system, including us) is moving in an orbit around the center of the Milky Way, and it is moving at the brisk rate of 486,000 miles per hour. It takes an unfathomable 226 million years for the sun (and its solar system) to make the full circuit around. The last time we were at this position was 226 million years ago, and dinosaurs ruled. The earth travels at 67,000 miles per hour in its orbit around the sun; a snail's pace compared to our galactic romp. See link.
