...is more than 1,100 miles per minute, or 18| m. per sec. The equinoctial, or tropical year, which is the interval between two successive returns of the sun to the same equinox, consists of 365 d. 5 hrs. 48 m. 49 sec. The difference between the equinoctial and the siderial,...

...between two successive returns of the vernal equinox to the same meridian is called a sidereal day. The interval between two successive returns of the sun to the same meridian is called a solar day. The sun completes an apparent revolution about the earth in one year, or 365 days...

...day, expressed in solar time, we have the proportion 360° 59' 8".3 : 59' 8".3 :: one day : 3m. 65.9s. Hence 24 hours of sidereal time are equivalent...and mean solar time, is called the equation of time. cate more than 12h. and sometimes less than 12h., the difference being equal to the equation of time....
