The galactic year, or cosmic year, is the duration of time required for the Sun to orbit once around the center of the Milky Way Galaxy. Estimates of the length of one orbit range from 225 to 250 million terrestrial years.
In relation to the base unit of [time] => (seconds), 1 Sidereal Years (Sy) is equal to 31558149.504 seconds, while 1 Galactic Years (gal) = 7.25328E+15 seconds.8840000000000 Sidereal Years | to common time units |
