Anomalistic Year
Related Category: Astronomy: General
(nm´´ls´tk), time required for the earth to go from the perihelion point once around the sun and back to the perihelion point. It is 365 days, 6 hr, 13 min, 53.
Anomalistic Year
The perihelion is the point of closest approach between a planet and the Sun. The time at which a planet reaches perihelion provides a convenient measurement of the duration of the orbit.

Anomalistic year, the time of the earth's revolution from perihelion to perihelion again, which is 365 days, 6 hours, 13 minutes, and 48 seconds. -- A year's mind Eccl., a commemoration of a deceased person, as by a Mass, a year after his death. Cf.
An Anomalistic year is the time (365 days, 6 hours, 13 minutes, 48 seconds) in which the earth (and similarly for any other planet) passes from perihelion to perihelion, or from any given value of the anomaly to the same again.
anomalistic year (NASA SP-7, 1965) The period of one revolution of the earth about the sun from perihelion to perihelion; 365 days 6 hours 13 minutes 53.0 seconds in 1900 and increasing at the rate of 0.26 second per century.
The anomalistic year is the mean interval between successive passages of the Earth through perihelion. The sidereal year is the mean period of revolution with respect to the background stars. (See Julian year; year, Besselian.) [S92] ...
The perihelion and aphelion are precessing, advancing eastward along the ecliptic about 11 arcseconds per year in relation to the fixed stars. This is the difference in arcseconds between the sidereal year and the anomalistic year.
For the Earth, the following alternatives exist: sidereal period (referenced to fixed stars) of 365.25636 mean solar days; tropical year (referenced to the equinoxes) of 365.24219 days; and anomalistic year (referenced to the perihelion position) of ...
