Timely motions of the earth
Earth reaches perihelion, the closest it will come to the sun each year, the earth perihelion does not occur on the same day or time, the farthest away it will be from the sun and also different times each year. The Earth’s elliptically shaped orbit around the sun is gravitational perturbed by the Sun and the moon, resulting in a different perihelion each year.
