Anomalistic Year, a year of 365 days 6 hours 13 minutes 49.3 seconds, thus exceeding the sidereal year by 4 minutes 397 seconds. This is owing to the fact that the earth takes 4 minutes 397 seconds in travelling from perihelion (or point nearest the sun) to perihelion, because the longer axis of the earth's ellipse makes an annual advance of 11.8 seconds.
