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 Hipparchic Cycles (HC) is equal to 9593424000 seconds, while 1 Galactic Years (gal) = 7.25328E+15 seconds.140300 Hipparchic Cycles | to common time units |
