Galactic Tick Day is an awareness and education day that celebrates the movement of the Solar System around the Milky Way galaxy.[1][2][3][4]
The day occurs at a regular interval of 1.7361 years (or 633.7 days),[5] which is called a galactic tick. The interval is derived from one centi-arcsecond of a galactic year, which is the Solar System's roughly 225-million-year trip around the Galactic Center.[6] One galactic tick is only about 0.00000077 percent (1/[360 × 60 × 60 × 100]) of a full galactic year.[7]
