Of course, there's more motions than Earth's daily “spin” on its axis to consider.Besides rotating on its axis, the Earth is moving around the Sun, the whole Solar System is moving around the Galaxy and the Galaxy is moving through space!
We know the Earth is moving in nearly circular orbit around the Sun. We are moving along in this orbit at almost 30 kilometers per second, or just over 67,000 miles per hour. Sound fast? Hang on: it gets even faster!
Our Solar System is tucked away in an arm of the Milky Way Galaxy. Our galaxy is rotating, and we are rotating around the galaxy's center at about 220 kilometers per second (490,000 miles per hour!)
Our Milky Way galaxy is part of a cluster of galaxies we refer to as the “local group.” Together, they are cruising through space at an astounding 1,000 kilometers per second. It seems that we're in a hurry to get wherever we're going, so the next logical question would be “where are we going?”
Halverson's work even attracted the attention of Bear McCreary, a composer who wrote the music for TV shows Battlestar Galactica, Eureka and The Walking Dead. He scored Halverson's for fun.
