A year is the orbital period of the Earth moving in its orbit around the Sun. In astronomy, the Julian year is a unit of time; it is defined as 365.25 days of exactly 86400 seconds (SI base unit), totalling exactly 31557600 seconds in the Julian astronomical year.
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 Years (yr) is equal to 31536000 seconds, while 1 Galactic Years (gal) = 7.25328E+15 seconds.| 27000 Years | to common time units |
