The time it takes for the Earth to go from one point relative to the stars to the same point again, i.e. to complete one revolution around the Sun. In terms of observation, it is the time it takes for the Sun to complete one revolution around the sidereal sky. Because the vernal equinox moves from east to west, the sidereal year is slightly longer than the solar year, which is measured by the vernal equinox, at about 365 days, 6 hours, 9 minutes, and 10 seconds.

地球が,恒星に対してある点から再び同じ点まで戻る時間,つまり太陽の周囲を1公転する時間。観測のうえでは,恒星天に対して太陽が天球上を1周するに要する時間。春分点が東から西へ動くため,恒星年は春分点によってはかられる太陽年よりやや長く,約 365日6時間9分 10秒である。
