A cop stops a physicist speeding. He asks, "Do you know how fast you’ve been going?" The physicist answers, "Well, officer, our galaxy is moving with a velocity of about 600 km/s relative to the Local Group, our solar system is moving with a velocity of roughly 828 km/s around the galaxy, the Earth is moving with a velocity of 30 km/s around the Sun, and we are moving around the Earth with a velocity of about 465 m/s.
