Galactic Tick Day

Our planet Earth, along with the rest of the solar system travels around the galactic center of Milkyway galaxy every 225 million Earth years. One centi-arcsecond of the rotation is called a galactic tick. A galactic tick happens every 633.7 days or 1761 years. Galactic Tick Day is set aside to acknowledge our sun’s motion, our progress around the home galaxy, and to celebrate humanity’s knowledge of this motion! 11:00 A.M.
